Ive experienced left side pain off and on for several years now which is made worse by eating. It completely debilitates me as when the pain comes on it causes me to curl up in a ball to make it any better. Had laparoscopy done by gyne showed nothing. The past 3 weeks have had constant diahrrhea 5-10 times daily, constnt heartburn, sudden onsets of vomitting and fatigue, i also found my right superclavicular lymph node is swollen and I have been getting frequent bad headaches the type that hurts more with movement. My doctor keeps telling me I have a virus and my body just needs time to get over it. Im sick of being sick!!! Can anyone please give me some ideas as to what this could be as Im sure its not a virus after 3 weeks.
