I have recently been diagnosed with BFS after a thorough neurological exam and test etc. I have painful cramps with my twitches. For the first time today I had chest pain. It almost felt like my heart was twitching or doing something very strange. I had pain there for a few seconds which this occurred and it went away. Has anyone else experienced anything like this before?Also, I get pains and twitches in my neck. It almost feels like my neck is tight or constricted. Is this a normal symptom of BFS? Thanks for your help.
