A month ago, I was diagnosed by my PCP with Pleurisy. I started having pressure pain in my chest, around my rib cage, back, and arm inflammation. I had a chest X-ray, which was normal. The anti-inflammatories were not working at all, so he prescribed me Prednisone, which helps. I am almost done tapering off the prednisone, (40mg for 3 days, 30mg, 20mg, 10mg), but I still feel inflammation, especially near the back of my lungs. The doctor said if I still have symptoms, he will send me to a Pulmonary. I am just curious of why I don t know the cause. Most people it seems had a cold, flu or pneumonia. I have not been sick. I was sleeping in a strange way on my stomach with my arm stretched out over my pillow. I thought maybe this contributed to the rib pain, which progressed to pleurisy. However, this seems unlikely. Should I be on antibiotics?
