I have another hospital appointment soon and I was wondering whether I should mention my stomach ache and nausea. Does anyone else experience nausea and stomach aches when you eat and during the day? This last period my stomach aches came back (they disappear for a few days at a time) bad before my period and after they normal clear up while I'm on because I have other pains. Do you ever get aches like you've pulled something and feel like you are really really weak and fragile? This morning my ribs felt like they were being pulled apart. Are these common symptoms of endo or are they ibs?? Because my stomach aches and nausea and weakness started after I had a tummy bug.
