HelloI've had Botox injections in my shoulders. The first round was approximately 5 weeks ago on my left side. The second series was to my right side about 3 weeks ago. I feel awful! Relentless headaches that don't respond to anything. Pain in my neck and shoulders that doesn't go away. My shoulders are so weak. I struggle to make it to work each day. I feel like I have a terrible virus. When I went in for the second round I shared my symptoms and he (pain management doctor) indicated those responses to the treatment was rare. Then I stumble on this site. When can I expect relief? I'm in excruciating pain.Thanks foe listenung.
