My 60 yr old brother was recently dx with progressive MS. Within the past couple of months he has developed severe hand tremors and can barely walk. His speech is also affected. He is in remission of bone and blood cancer. He called me stating that he doesn t have a headache, but is c/o a throbbing in his head, nose and mouth, like a pulse but has no other sxs. He is taking copaxin IM 3 times a week for the past 2 months with no ill effects.
