I was tripped a week ago in a 5k and fell on my right side sustaining road rash. Last Thurs I went out for an easy run and could not even go 1 mile before having to stop due to increase pain on right outer rib area. I tend to hold my sneezes but have a lot of pain as a result. I currently take 800 mg of ibuprofen and ice the area. I'm not sure if I strained the intercostal muscles on that side. What should I do at this point, I'm supposed to go back to work on Monday. I work in a hospital with patient care in physical therapy.
