Hey there - I think we might have found the problem - The Cymbalta that they had just started him on....He did not take it last night nor today and he has not had the weakness nor the spasms....Could be a coincidence but it could (which I belive was and is the problem) So it looks like we are 2 for 2 meds now - both the last 2 meds he had problems with. Apparently too it does not mix with the Lyrica he is on. Sooooooooooo looks like we might be switching a few things around here but hopefully will get him off of some of this crap. He does not like to take medicine as it is and the less the better. He's been doing the blocks which have been giving him relief so with the change in meds and blocks hopefully we'll find a combo that works!
