The other problem at the moment is the return of the twitches and sharp pain.

Yesterday on the train, the pain in my leg was really bad, and it wasn't the usual pain, it was a very sharp pain, then I was getting sharp chest pain and sharp here and there pain, I don't know why, and now the nerves have started off twitching uncontrollably again.
I am worried that I might do something catastrophic like dropping a cup of tea!
