it is now three weeks since falling on the floor as i was attempting to run from a dog-i fell directly on my chest and abdomen-using arnica , only took extra strength tylenol for a few days, doing full breathing exercises frequently during the day to avoid pneumonia possibility, feel like I have had 5 simultaneous mammograms in the left breast, did not go for films (fractured 2 ribs 5 years ago and the first films revealed no break, terrible pain persisted and second films revealed the actual fracture, so I did not go right away this time), however I have abdominal bloating, and alot of belching which is unusual for me, stool and urine are not discolored, no vomiting, diarrhea or constipation,; my mom was diagnosed with pancreatic cancer about 6 months after a nasty fall on the pavement, so I must admit that this is on my mind, although I realize that not everyone who falls has a subsequent cancer dx. Any advise for the bloating and what symptoms would make xrays advisable?thank you very much!
