Any pain when you breath in or in the back of your right shoulder? Get two fingers together, breath I deep and push up under your last rib on the right. If it hurts a lot, there is a chance you might have gall stones. My attacks would come on so suddenly, it was a big mush of agony, nausea, vomiting, light headed ness and the shakes. See a doctor, demand tests! Best of luck!!!! Xo
maybe you could have a water infection this can cause sickness and severe pain please see a doctor
