Both of you need to see a spine surgeon for evaluation and tests to determine if you are having any kind of spinal issues going on.
Numbness and tingling are signs of nerve compression and there are various conservative treatments that can be done to alleviate the nerve compression that do not involve surgery of any kind.
But, without a diagnosis, treatment can't begin.
No doubt an MRI would be ordered to see what is going on with your spine, if anything.
Muscle pain should not last 2 months, unless your exercise regimen in continuing to keep the muscle strain inflamed, OR it is not a muscle, but rather a disc problem that was caused by something you did at work.
Only and MRI will be able to tell that.
Your doctor is quite wrong in saying that nothing can be done for a pinched nerve.
A good regimen of physical therapy can relieve the pain and allow the pressure to be removed from the nerve. If necessary, a cortisone injection can help relieve the pain and allow healing to occur.
But, it all depends on what is wrong and only a spine surgeon can give you that diagnosis.
It is true that many chiropractors can create further havoc with the spine, but there are some good ones out there as well.
My personal feeling is to stay as far away from them as possible. I've seen far to many people and know far to many people that have had their spinal problems made seriously worse by chiropractors.
Unless a spine surgeon directly told me to use a particular chiropractor, you would never get me near one.
You need to see a spinal surgeon for diagnosis, either an orthopedic surgeon that specializes in spines only or a neurosurgeon that specializes in spines.
Good luck
