I would like to know if this is medical malpractice?

I am in the mid 50s. I was having severe upper stomach pain . I could not stand up straight. I went to the emergency room I had 3 ct scans. X rays and bloodwork. I heard the dr joking about the pain said it was muscles he had the nurses laughing So he came into where I was,said nothing was wrong gave me a little some thing to ease the pain. A week or so later I had the problem still This time even worse. I went back got the same mouthy intern. said he doesnt know ?everything shows nothing is wrong. The dr came in I had pancreatitis I couldnt eat or drink anything for over a week They told me to stop taking a med I was on and that was that. I went to my own dr She had me see a specialist I was admitted from his office to have my gall bladder out. I had a stone near the size of golf ball sitting on the drainage port. I had emergency surgery. I have the reports after getting a 75,000.00 bill There was no mention of a gall stone in either report intern and the overseeing dr put down But there was a report given about the gallstone on both visits. It was overlooked in the emergency room I suffered with alot of pain dehydration vomiting from the first visit to the next about a week. Even the specialist who did the surgery noted that the report given to the er mentioned the gall stone but it was overlooked I was misdiagnosed.
