Morphine
"Started taking oramorph after staying in hospital with a prolapsed l5/s1 disc. Urgent surgery is required within 4 weeks so was given 30mg of morphine slow release also. I couldn't walk because of spasms in my spine but now I am mobile. However, I seem to suffer from itchiness. This is the only problem I have. I also take diclofenac, gabapentin and paracetamol."
