About 2 1/2 weeks ago I received Botox injections in my head neck and shoulder blades. My shoulders hurt and feel like I have rocks in them. I can only put my head down to read for a few minutes. Yesterday I was trying to pick up colored pebbles with kids and could only last about 5 minutes and the pain after lasted quite awhile. I thought after treatment I would wait to see if it got better but it seems to be getting worse. What should I do?
