I developed an upper respiratory infection in September and was prescribed a steroid shot, cough medicine, and penicillin. My flu-like symptoms improved and even my cough. However, it is now November, and I still have this unusual cough that will strike anytime. Just as my onset started, it tends to be associated with the right lung. I also have wheezing associated with it, pain around my right should blade, and am very tired. I have also noticed some symptoms of fluid retention, joint pain, and food not going done real good.
