Don't be afraid to re-evaluate and renew your knowledge about yourself and your needs.
numbness in the area following it. Nerve regeneration is a strange thing.
It can take days, or weeks, or even years. So it is possible that the pain
you are experiencing may be from surgery. However, without a proper exam
surgery and fusing vertebrae, it can cause wear on places above and below
the surgery. While the issue may not be the surgery itself, it may be
because the biomechanics have changed. A good evaluation from a
chiropractor can help to see which structures may be irritated and why.
There are several questions to ask;
1) Where exactly is the pain?
2) Is it low back , mid back or hip region.
3) Does the pain occur in bed or anywhere you lie down?
4) What type of pain; dull, sharp, achy, radiating...?
5) What part of the back was fused?
Possible answer with out knowing the facts are;
1) If it is only when lying in your bed, the mattress would likely be a major possibility.
2) If it is in the hip or low back region it could due to fixation of the hips and seeing a chiropractor could take care of that.
3) General treatment could include use of a CBD cream, Sombra cream, TENS unit.
4) Do some stretching exercising in a pool.
My suggestion would be to see a Chiropractor in your area to get an initial evaluation to see if it is treatable or need a referral back to your surgeon.
Bottom line you should be seen for an evaluation because there are many possible answers to your question.
