Thank you for the input.
The feeling of numbness is related to nerve impulses. It can be due to low calcium or electrolytes, B12 or other vitamins or use of alcohol, tobacco, if you take any. The other probables are thyroid
diseases, diabetes, pinching of a nerve or other nerve diseases. When it is coming on lying or sitting, there can be nerve impingement from posture. In some cases it can be due to low blood supply to a part. The pain in the shoulders can be due to a different condition. It can be due to arthritis, adhesive capsulitis, rotator cuff problems etc. Initially NSAIDs like ibuprofen or aspirin, physiotherapy
can help. As it is continuing for 3 months I would advise to get it examined by doctor. If he thinks necessary, he can advise X ray, scan, blood tests after examining you.
Any query, please feel free to ask.
It will be my privilege to assist you.
