One week ago I injured my sternum while cleaning replacement windows . The bottom window actually fell hard on my chest. I did see the DR, underwent exam, EKG, Pulse Ox, CXT, and Xray with attn. to Sternum. It hurts all the time especially with deep breaths, coughing, sneezing, laughing etc. I am sleeping upright but fitfully due to pain. My PCP callled the next day regarding the xray saying that he was baffled because the xray showed a healed old fractured sternum. He said and understandably that the healing was impossible but I have never injured my sternum before. At first Dr. ordered Extra Strength Tylenol to no avail, and then Oxycodone 5 mg. which I am not taking as it did not relieved the pain and only made me feel loopy I first started with heat and now ice. Any suggestions? I am a 58 year old female, 134 lbs, active prior to this ie walking 4 miles daily with a Hx. of Rheumatoid Arthritis.
