Hi,
I have gone through your query and I would say, it is not due to age.
If you have a burning sensation, more so in the palms, it could probably be neuropathy. However, if you feel the pain moving from your shoulders, and increasing with moderate home work, it could be
spondylosis.
I would usually suggest an X-ray if it were to be spondylosis.
In your case, I strongly suspect
peripheral neuropathy due to decreased essential vitamins. Normally I would prescribe B-complex vitamins along with
folic acid for a month and follow up later on the symptoms. If the pain is severe, I would prescribe
NSAID pain killers to reduce, especially in the night.
Your concern for taking Over the counter medicines is appreciable. B complex vitamins do not have any side effects or toxicity. You can get a prescription from your doctor
Along with it a improved nutrition should improve your overall symptoms. If you having feelings of
stiffness, try moderate exercise.
If you have any further queries, happy to help
