Burning in legs and hands

[Adel]

Please help me. Sometimes I have got strange hot feeling in my arms or legs and my hands and legs were cold and wet for a few days. Can this be caused by anxiety? Often I feel very hot for no reason and sometimes I feel really cold. My back hurts. And I’ve sore throat and dysphalgia for two months. My gums are little swollen. And that thing under my tongue hurts. I was in hospital two months ago and all the tests were good. Since three weeks I feel I have phlegm in my throat and sometimes in my nose. And now my fingers prickle.

Can be caused by anything.
I have nerve damage in my back and my feet go cold a lot as do my hands.
