Hello. I have Sickle cell disease and I have chronic daily pain, but I have recently noticed that for the last year I ve had runny & stuffy nose, swollen lymph glands, and low grade fever. It has been an ongoing problem. I can t figure out what it is. I am currently taking Morphine 60 mg, Percocet 10-325 mg, Folic Acid 1 mg, hydroxyurea 1000 mg, neurotin 600 mg twice a day, zantac 50 mg, ibuprofen 600 mg, and potassium. I was once diagnosed with MRSA. I notice that I have a very high number or sickle cell crisis as well. No doctor can seem to figure out why I am having pain daily or why I m having the runny nose and swollen glands. I am diagnoses as sickle cell SC. My hemoglobin is usually around 7-12. I do have a CBC and various of other blood test don t monthly. I m not what could be the cause of all of this, but I need an answer please. Thank you.
