I have had upper right back pain since the first of January. The pain was so bad I finally went to emergency room. They did blood work up-neg. they did chest ex ray-nothing, they did an EKG of my heart- nothing. Due to a vascular problem where my veins spasm when trying to get a deep vein, after several tries to do a cat scan, they gave up and said my primary would have to order a pic line for the cat scan. I went home with pain pills. 2/7 I developed 104 fever lasting 3 days, now comes and goes. I still have back pain, and I am coughing with just today a small amount of dark thick stuff coming up. Chills, headache, can t eat, can t stay out of bed due to chills, fatigue. Since my doctor is booked weeks out, I don t know how to help myself except rest and hydrate, yet I don t feel I am getting better. My friend said to try this because she is worried.
