I was diagnosed with soft tissue sarcoma in January. Surgery was done to remove a tumor on my upper right rib. They told me they got it all, and I return to see them every four months. My problem is that I have ran a temp of around 100 for two months. The last two weeks I have experienced strong to severe pain across my shoulder blades. It feels like my lungs hurt. My family doctor has given me antibiotics and still the fever persists. He did a chest x-ray and said it was normal. I feel like I get light-headed and could collapse.
