What Causes Tingling Numbness Starting From Legs, Radiating Throughout Body?
Phenytoin sodium is the problem or Vitamin B12 deficiency.
Detailed Answer:
Hi there, sorry to know about the problem your husband is facing for one year. There may be a variety of causes for the problem particularly in old ages. But I think the numbness tingling sensation that he is having is a side effect of phenytoin sodium. I would suggest you to consult your doctor and ask him to gradually shift him from phenytoin to other newer anticonvulsants with lesser side effects. Please do not stop the drug suddenly by yourself as that will cause more problem. Phenytoin has to be gradually tapered off and other drug has to be gradually build up. Once phenytoin is omitted for 15 days the symptoms may decrease considerably.
I also suggest you get Vitamin B12 test done. Vitamin B12 deficiency can cause numbness and tingling.
