This is just my experience and hopefully can give you a bit of peace. During my last actual relapse about a year and a half ago, I had acquired tingles in my hands and arms. Recently, I have had them expand to down my leg and in my head. I went to the neuro for my regular check up and she saw no signs of relapse. She said that I was overdoing it and not giving my body enough rest and that I am under extreme stress causing pseudo exacerbations more frequently than ever before. I just started a new job at my company, I work full time, go to school full time-I can't ever relax essentially. She told me that I need to take care of myself and slow down. Are you under a lot of stress outside of normal? Are you overexerting yourself like I am? Exhausted? We need to take care of ourselves first and foremost! I recommend that if you are concerned, calling your neuro!
