Over The Weekend, I Had Attended A Rave And For

Over the weekend, I had attended a rave and for the first time ever I had taken ecstasy. I had a total of 3 tablets that night. Its been 3 days since that night and yet I still feel a tingling and numb sensastion on my right arm. I can still do everyday things but I feel weak with my right. I tried to see if it was just bad circulation since I did sleep on that arm that same night and tried to lift weights. I struggled with a ten pound dumbbell. My thumb, front forceps, and biceps seem to be affected. Is this a side effect? Will it go away? If so, how soon? Was it just a bad batch?
