I"m so sorry to hear you are in so much pain. The only thing I can recommend is to keep going back to your GP and see if they can get your referred a bit quicker to the hospital/surgeon. I would also seek some specialist advice about your pain relief options as I do believe there are some things that could be taking - obviously not all the time but just when it's getting too hard to handle, kwim? After my c/section my wound got infected and there were several different types of pain relief offered to me at the time.
