For me it was simnilar. Finally after a week of feeling awful and being told it was a bleeding ulcer I went to the emergency room because I could hear my heart beating in my ear. Sounded bad. Turns out I was super low on hemoglobin. They still spent three weeks telling me it was an ulcer and even sent me home once, but it turns out they finally saw a "shadow" on my scan. At that point I said, nope, not this hospital that missed it for weeks and trransferred to the city. They got me into remission so no regrets there! You are definitely not alone, it is annoying for sure. Let us know if there's anything we can do to help! Keep on keepin' on, DPM
