I had botox about a week and a half ago. Probably about 4 days after the left side of my neck started hurting so bad. It is not weak, just in pain. I have a 1 year old baby and it is too painful to pick him up. My doctor says this did not come from botox. I also experienced nausea, which she said did not come from botox either. I looked them both up on the botox site and saw they were side effects. Long story to say can anyone offer tips to relief the pain?
