I think I fractured my pelvic bone, its been two weeks and the pain is slightly worse. Right above my right check on the top of my pelvic bone, is a bump and occasional its pretty painful. I fell from an elevated height, and didn't notice the pain till a view days later. I am only 28, so my biggest question is: Is there anything a doctor can really do? I am still mobile and can do all my daily grind activities. Obviously there is no cast that can be put on it! Are there some home remedies or vitamins i should be taking that will help the healing process? Are there bodily signs i should look for that may be life threatening? I havent been sick but shortly after the incident i have had a cough and some mucus buildup.
