Had spasms so bad just reaching for something would drop me to the floor in pain get shots every month for 5a months and only had a few spasms since getting the shots does not hurt unless you get them in top of shoulder to neck area just a little disconcert but since I been getting the shots able to function again as pt in does not help me much I can move a little better but brings on dull pain for a day but it might not do that with anyone else you have to make your own decision
