I had Boxtox injection in my neck for head tremor's which was causing pressure in my head that I could not take. It's been 2 and half months and my side effects can't hold my head up is still with me. I went to the doctors which took 10 weeks because he so busy. This Dr. told me that the side effects will go away but in the mean time I cannot get another injection until the side effects go away. I'm just nervous that my head pressure and tremor's will come back before the next injection. Did anyone have to wait for their side effect to go away before the next injection? Is there anything I can do? Dr. also gave me muscle relaxer
