Is There Any Alternate Other Than Baclofec As Muscle Relaxant?

I have scar tissue on an area in my brain that controls my leg reflexes, I forget exactly what it s called but it s the corticospinal something I believe. My legs get tense and stiff and it worsens if I am thinking hard about something, my neurologist said that s because your thoughts run through the same area of the brain apparently. If my legs are tense and not completely relaxed before I go to bed then I will get a couple hours of deep sleep but when I wake up after a couple hours deep sleep I will only get light sleep after. If my thigh muscles are loose enough I can sit down for half an hour and when I stand up my thigh muscles will stretch out and loosen up and then I will feel a deep relaxation and tiredness in a part of my brain and I can tell that I will get deep sleep again. It s like my deep thigh muscles are compressing a nerve or something and it s affecting my brain and preventing it from relaxing and getting deep sleep. Can somebody please try and make sense of this for me? Can anything more be done to relax muscle other than baclofen which I am on but isn t having a big effect?
