I have been experiencing numbness and tingling in my right leg and foot for a few weeks now also in my buttock,it is particularly bad in the morning I can hardly bear to sit on my right buttock and prefer to lean across my work top,I have also been experiencing muscle spasms in the top of my left arm and I cannot reach round my back without pain and on occasions my arm has actually collapsed on me whilst holding something.
Dear Sir/Madam have gone through your query and read your symptoms. In my opinion, these symptoms could come from the back, there could be compression on the nerves arising in the back and traveling to the leg, you should follow these points1 do not exert too much, 2 consult your doctor and get investigated.3 MRI of the LS spine needs to be done.4 Continue analgesics and Pregabalin under supervision of your doctor. I hope that answers your query. If you want any more clarification, contact me back.
