Numbness of hands i likely due to the nerve compression at the wrist level. This is also known as carpal tunnel syndrome.
You should try wrist brace daily overnight to rest the nerve adequately.
Symptoms should improve slowly.
Crawling sensation in legs is likely due to the nerve problem as well.
Abnormal sensation is due to the inflammation of the sensory nerves supplying your legs.
Underlying medical causes like diabetes, vitamin B12 deficiency, thyroid disorder should be checked.
Nerve boosting supplements like vitamin B12 1000 mcg daily, vitamin B6 50 mg daily, Alpha lipoic acid 600 mg daily should help with such symptoms.
