Just had my first set of shots yesterday and woke up this morning with a very sore neck, shoulders and upper back. Also had a little bruising on the right side. I see my Dr. again on the 25th of Oct and if my pain has not gone away I will not take anymore. I the pain I was having is nothing compared to this. I at first thought this was a normal side effect but now and not so sure. If building up the muscles are going to cause such as this I would rather have the titled head. I am truly glad I decided to research this and glad that I found this forum!
