muscle spasm
"Was prescribed Baclofen 20 mg and allowed to take one half to one pill per night at bedtime. A few days ago I bent over and couldn't get back up. I am active, not old, and fit. Apparently I pinched/compressed a nerve(s) in my sacral area. I was taking methylcarbanal with little relief. My PCP have me a Toradal shot and Baclofen. Wow! Baclofen worked great but 20mg gave me a hang over the next morning (no headache). Woozy, drunk and floaty feeling. Decided it was best not to drive and stayed home. While I am grateful the Baclofen worked I will be taking 10mg from now on when needed. 20mg is just too strong for me at 5'8 and 140lbs."
