As a retired Paramedic when people used to ask us if they should have called us we said "Yes". Any time you consider going to an E.R. because something is wrong to you, go. It could be an ulcer, inflamed colon or even a gall bladder attack. If Tums did not cut it and it feels different to you call your doctor. I had a bad stomach ache in May. Tums, Phenergan or even Zofran did not work. It got worse and I went to the E.R. the next day I had immediate surgery to remove my gall bladder which was so inflamed it was affecting the surrounding tissue. Call your doctor if you can before you go though and ask if you should go. If you cant get the doctor, go anyway. Take care baby! 🙂
