Yes, my husband has alot of pain in his left arm. Even though he too can not move it. They have him on tylenol 3 for the pain, which seems to take the pain away.
Stroke is so very different in every person. I have read and read on stroke. I have come to the realization, it takes time to heal.
When my husband suffered his stroke, they had to remove a flap from his skull to let the brain swell. He wore a rubberized helmet for 6 weeks. Then they replaced the flap.
My husband has now been taken off trazadone and he just takes paxil.
Does your dad have his arm in a sling? My husband wears a sling when ever I move him, to make sure the arm does not drop. When he is sitting I take it off. Sometimes too I find if you rearrange the arm the pain may go away.
It took months before they could even work on his arm it hurt him so bad.
Never lose hope.....................................
