I would guess that the baclofen is not causing your increased pain and stiffness; it just may not be working. I have also experienced increased spasticity while on 60 mg. I am now down to 10 mg, and I am experiencing more pain but the stiffness is about the same. So I suppose it was helping me a little. I will be completely off of baclofen on Monday, and then will start taking a low dose if zanaflex on Friday. He want me to be off of baclofen for 5 days before I start.
