First of all - you should only be getting the injections at the MOST every 3 months.... no sooner... And the first session they are supposed to go weak with the mixture and see if that is enough for you - if not (after 3 months) they will go with a stronger mixture.

I am getting this for my neck, shoulders, upper arms, and upper - mid back this Thursday the 16th. I will let ya all know how it goes. I plan to use a lot of ice afterward - every hour for 15-20min the first night for sure.

talk with ya all later! (mine is not for headaches its for muscle spasms and tight muscles). And I heard the shots in the face etc. do hurt more than the ones in your neck and back etc.
