Hi Sair, I keep getting really bad ache's like you have just described. I discovered i usually get them after drinking, whether i have a small amount of alcohol or a skin full!! I STILL wake up the next day feeling like i have gone 10 rounds in the boxing ring. Like this morning, i had quite alot to drink on Saturday night and yesterday and today i am suffering like hell. I too had a large meal last night, which always helps my hangover, but now am wondering if this is linked?? Its all across my back, top of shoulders, around my kidneys and stomach. I keep meaningo go to the doctors for some kind of kidney check up as it often feels worse around this area. Does this sounds anything like your symptoms??xxx
