Jeez Erin! It's like you just can't catch a break, isn't it??!! After that horrible fall and now this...
I'd do the baclofen, and do the whole pill this time! If that doesn't help, call the doc. You might be able to get a different scrip for the pain, but the baclofen will do the trick if it is spasticity.
What amount of baclofen are you prescribed a day? I am on three times a day, although there are many days when I don't take them all. When I am spazzing, I am on them as prescribed or better, as in every six hours or so.
Hope you feel better soon! Let us know how it goes!
