Hi, my name is Romina, I have been on phenobarbital for over 16 years and I was wondering if one of the side effects was muscle tightness and pain in my arms and muscles.  I even have had frozen shoulder on the right side now I lay on the left side and it is painful.  Can you tell me the side effects of phenobarbital.
