My father has left side hemiplegia since 14 mnths, he avoided accupuncture, massaging etc treatments in hosp due to too much pain he was feeling.now he is on complete bed rest since 8 mnths, he even cant move his left body as well as he is always in looking towards roof position, now he is complaining puslating pain in his left leg which is swallowing now, his left side muscles became hard too. My question is that are there medicines or treatments doing which he cant feel pain while massaging or accupuncuturing etc. I heard tht these kinda pyralysis person feels pain due to nerve blockage. Any advice?
