Hello,
Numbness behind the head shoulders, arm (R) and legs commonly occur due to neurological disorders or developing
peripheral neuropathy. It is detected in people suffering from diabetes,
fibromyalgia, MS,
nutritional deficiency, etc. If diabetic control your blood glucose level at all cost. The best vitamin for overcoming neuropathy is vitamin B1, B6, B12. Take food that is rich in it or supplements.
You are suggested to get clinically examined by a
neurologist. Get Blood tests, Nerve function velocity tests done, you may require to do performance tests & imaging tests too. Conservative treatment with
Physical therapy works best. Surgery may be recommended if required. Avoid addictions(caffeine, smoking, alcohol) if any. Take adequate sleep. Stay active & take healthy, home made balanced diet.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
