For the past couple of weeks i have been getting a burning sensation in my neck and chest,my neck gets very tight and i have the sensation of something squeezing on my brain at the base of my skull.Doing simple tasks causes me to sweat profusely,i also have the feeling of something stuck in my throat.The pain in my neck was so severe the other day it woke me up,after i awoke i was sick for about 30 mins.My doc said it was muscle spasm in my neck(i am not so sure)as for the thing in my throat he said"It's a red herring"(i kid you not).I also can't stop rifting.Has anyone out there had similar problems?
