When my leg spasms started it was in one muscle and that muscle was rock hard and hurt like h-ll...... then eventually both legs would be in such pain that i did not know if it were my muscle or bones... That is how deep the pain was. I had to have surgery on my hand when my legs were acting up, i was in the prep room for six hours because my surgeon found an anuerysm on a man he was doing surgery before me, so it bumped me. I could not eat or drink and had to lie in this hospital bed and kept tossing and turning because my legs hurt so bad, i started crying. When i got home i took my baclofen and was like brand new.. I am very greatful i do not get spasms like that in my legs anymore.
