"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&#039;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."
