You need to go to the doctor and be examined..Only with lab tests can he be for sure..Are you on any meds or taken anything illegal that could be causing a reaction? How long has this been going on? Take notes and take to the doctor..Do you hurt anywhere, does it happen when laying down,how is your walking, do you feel any foot drag, how is your hearing, taste, sight..Write everything down and take to the doctor..Pay close attention so that he will have a better history..Best of luck to you..Call doctor today, ok...
