I was trying to refill one of those weed killer container, because it had pressure on it, it was difficult to unscrew. I felt a pop on the right side under my breast . It hurts to bend over and a little trouble breathing. I want to know if I fulled a muscle or cracked a rib or something.
I think you should get yourself checked by an orthopedic specialist. If you can take an x-ray of chest it will help us to know better. Please do not try self-medication. Kindly follow the physician guidelines. meantime you can do slow deep breathing exercises by keeping hand onto the area where it is painful and do little icing for pain relief.
