30th January 2013, the day following my operation on my lung, I reported a feeling of pins and needles/numbness from toes up to the my groin. I was still on morphine and was vomiting and had a dry mouth, also quite a severe pain in the back of my neck. I was taken off morphine and, the nausea and pain went but, I still have this feeling from groin downwards. Is there any cure please?
