So About 2 Weeks Ago I Had Constipation For About

So about 2 weeks ago I had constipation for about a week,I couldn’t use the bathroom and I was constantly throwing up.. ,after a while I felt better ,I thought it was gone (I don’t know if this will help with the situation I’m in right now or not).Anyways every time I eat something big such as a burger ,or just simply ice cream or just a meal,about 2-3 hrs later I’d want to throw it up ,which ends in a result of me actually throwing up chunks..this has been happening for about 2 weeks now ..
