This is a bad one!! I have not had this since being diagnosed, but when I was in college I cracked two molars from grinding! Get a mouth guard. They are expensive from the dentist as insurance doesn't usually cover it. You might try the over the counter type. I have no idea how well those work. As for relieving the spasticity, I can't really help there. I just take baclofen and that works for me.
I hope you get that taken care of soon.................(smiling to show off my two gold crowns to repair those molars)
I go through periods of grinding.....I am not good about using my mouth guard all the time. I use it when I grind. I should use it all the time but I don't. My worst period of grinding was in college...despite loving it, it seems that stress must have been the culprit.
Yes, baclofen can make your legs "weak". You need a certain amount of spasticity to walk (that ability to keep a muscle tense to bear weight). There does seem to be a fine line between reducing spasticity but not so much as to make it difficult to walk. It seems that some have to really work on tweaking meds and dosages to find that right balance. I actually have very strong legs (thanks to some very specific PT ) and don't have that problem. I have pain from spasticity in my left leg. I have some nerve problems, again that left leg doesn't always do what it is told. It likes to trip the right leg and it likes to just give out.........crash!!
I only use baclofen as needed. I don't always need it. So, I am no expert there. I am sorry.....I don't think this was much help.
