Causes of numbness in leg

Question
I have been having problems.  From about my left knee down to my ankle I have a numbness on the top/shin area.  If reminds me of how my legs felt when I had a spinal for my c-section, and how my belly felt around the incision after my c-section, it just doesn't feel right, I can feel it, it just isn't right.
My ankle is sore, and my hip/buttock/low back is sore, so I am thinking a pinched nerve. I also have a cramp in my foot at times.
I went to a chiropractor today, he didn't seem to worried, he adjusted me and for a minute or two it did get a little less numb feeling.
My question to you is, does this sound serious or would you agree that a few adjustments can probably fix me up? (That is basically what the chiropractor I seen told me)
If it isn't from my hip or ankle what else could it  be?
I am 28 female caucasion, otherwise healthy.  I have been aching.
Thanks for all your help!

P.S. No known injury, I do sit on that leg, and have pretty poor posture, I sit at a computer, and sleep on my stomach which makes it worse.  I have been having a shoulder problem long before this started, I don't think it is related, but thought I would put it out there just in case.

Answer
Dear "Numb,"

Thank you for your question.  Believe it or not, you are the first person, in the years that I have been writing for this site, to use a pseudonym appropriate to a Dear Abby letter.  I found it fun to address you as "Numb" and am hoping as I say all this that it is not your real name!

In order to answer you properly, I抣l first need to give you some background on anatomy and physiology and how they relate to the chiropractic profession.  I抣l then offer my thoughts on how this may relate to the situation you describe.  

There are two branches or schools of thought in chiropractic.  Briefly, they are differentiated by whether they deal with the limited therapeutic approach for aches and pains (commonly termed "mixed" chiropractic because it represents a mixture of a chiropractor with a non-chiropractic matter) or a non-therapeutic approach to optimum body performance (termed "straight" chiropractic because there is no mixing of chiropractic with anything else).  My expertise is in non-therapeutic straight chiropractic.

Therapeutic "mixed" chiropractic is the older approach based on a split from the founding principles of chiropractic about a century ago.

Non-therapeutic "straight" chiropractic is the more modern of the two.  It deals with a particular, common situation called a vertebral subluxation.  This is not specifically the same as the findings referenced in your question, but they may exist together.  The spine is made of many bone segments which house and protect the spinal cord and the smaller spinal nerve branches that come off the spinal cord and exit between the bones.  These nerve pathways carry information or messages between the brain and the cells of the body.  These messages are essential for the life of the cells.  Without brain messages, the cells immediately begin the process of dying; i.e., they can no longer function the way they should to maintain life.

Because the bones are moveable, they can misalign in such a way as to interfere with the messages and, ultimately, the ability of the person to function at their best or express their optimum potential, whatever that may be.  People with vertebral subluxations are not able to get all they can out of life.

Vertebral subluxations can be caused by a wide variety of factors, what we'll generally call stresses.  These stresses can be physical (such as exercise routines, sleeping posture and mattress condition, the birth process, sneezing, falling down, etc.), mental / emotional (in its many forms, probably the most familiar use of the word stress), or chemical (such as pollution, drugs, food additives, etc.), which are, unfortunately, largely uncontrollable and regular parts of daily living for all age groups.  In short, a vertebral subluxation can occur for a multitude of reasons.

Tragically, vertebral subluxations are rarely obvious to the individual they affect.  They usually have no symptoms.  The reason is that most of what goes on inside you happens without your awareness.  For example, try specifically to "feel" your liver.  Try to be aware of exactly what it抯 doing right now.  You can't, so you can't know if it's functioning at its best or something less.  To complicate things, nerve pathways that carry messages of control (termed "motor" nerves) have no way of transmitting ache or pain messages, so your body function may be far from perfect and you'd not have any alerting signal whatsoever.  The branching of the nerve pathways is complex and extensive, making it exceedingly difficult to predict or determine exactly how the person will be affected.  For this reason alone, it is impossible for anyone to give you reliable answers as to a connection between the spine and specific symptoms of any kind, including the numbness you mention.  Anyone who does so is making a guess, at best.  Certainly, every part of the body must have connections to the nerve system so that vital information may be transmitted between the brain and the cells.  There are some who would attempt to review the possible nerve connections between a nerve root and specific organs or tissues, but this ignores the multitude of variables that determine the expression of function.  The question of how your individual body carries out the myriad of activities just to maintain life is enormous and would require your Creator抯 (or creator抯, for the agnostic) knowledge, or at least far more than our educated knowledge of the complexities of life.

Now that you have more information about the body and vertebral subluxation, how do you make use of it?  Well, first understand that this is not an explanation of why you have the numbness you described or whether it is related to vertebral subluxation.  Are there reasons for what you抮e experiencing?  Even though they may be beyond our ability to identify, yes, there are; but pinning them down is not relevant to the matter of whether you will benefit from being free of vertebral subluxations.  Vertebral subluxation is, in and of itself, detrimental to your life.  It is not valid or reliable to try to connect it to complaints of numbness, as you mentioned, or any other organ or tissue conditions.  In fact, the matter of making a diagnosis by correspondence is risky, in and of itself, but far more central to our discussion, it is not within the purview or objective of a non-therapeutic straight chiropractor.  

The only way to know if someone has a vertebral subluxation is to have that person抯 spine checked by a non-therapeutic straight chiropractor using a method of "analysis."  When a vertebral subluxation is detected this way, it is obviously important to correct it as soon as possible.  The term for this procedure is 揳djustment.?br>
Since vertebral subluxations are caused by so many different things, people choose to go to a non-therapeutic straight chiropractor on a regular basis to enjoy the most time free of the life-robbing effects of vertebral subluxation. There's a saying that straight chiropractic is not about your back, it's not about pain, it's about your life.  Each person has a unique potential in life.  With vertebral subluxation, it's impossible to realize that potential.

A key question to ask for your purposes, then, would be, Is someone with the numbness you describe better off with vertebral subluxation / nerve interference or free of subluxation / with the nerve channels open?  It is easy to see that having all the available nerve messages getting through is better than only some of them getting through, regardless of the person's situation otherwise.  It抯 not that you should see a non-therapeutic straight chiropractor FOR your numbness and other symptoms ?you should visit one in an effort to be free of vertebral subluxations, even WITH those symptoms.  Non-therapeutic straight chiropractic is not about diagnosing and/or treating this complaint or any therapeutic-model or medical condition.  It is entirely separate in its goal.  

In order to determine if you have a vertebral subluxation, it would be wise to have your spine checked by a non-therapeutic straight chiropractor - even if you still elect to have therapeutic attention or advice for your numbness.   

As I mentioned earlier, not all chiropractors adhere to this and it is important that you be able to distinguish which ones do if you're going to seek this type of service.  You need to understand very clearly that the practice objectives of therapeutic mixed chiropractic and non-therapeutic straight chiropractic are quite different, as described above.  What I can tell you must not be interpreted from the mixed viewpoint.  It appears, from the limited information you provided, that the chiropractor you have visited is of the therapeutic mixed viewpoint since the attention is directed at the symptoms.  As I said, there are significant differences between this approach and the non-therapeutic straight chiropractic model.  The matter remains, though, as I mentioned above, that attempting to connect specific symptoms, including numbness, to the spine is potentially guesswork.  You will know if it is a good guess, perhaps, if the symptoms disappear in a few visits, as had been predicted.  If not, you know it was a poor guess.  Either way, it is different from what a non-therapeutic straight chiropractor would do.  I will not, then, offer an opinion agreeing or disagreeing with the advice you were given but I will say that you should give consideration to having your spine checked by a non-therapeutic straight chiropractor, independent of the outcome with this therapeutic mixed chiropractor, for all the reasons we covered.  

If you are interested in finding out how to locate a non-therapeutic straight chiropractor in your area, please contact me at this site again or at [email protected].  You may also visit www.gschiro.com, a site that represents non-therapeutic straight chiropractic organizations on a state level.

I wish you the best in understanding the principles of non-therapeutic straight chiropractic.  It has been my pleasure to provide you with some information.

Sincerely,
James W. Healey, D.C.
