I went in with chest pain and told my doctor it was my reflux. "We don't take chances" he said. I was given nitro pills and patches for 14 hours. Failed the stress test and was referred for a cardiac catheter, which went fine, showing that I had no heart problems (great was my feeling of relief!) I laid down for 6 hours and then with the nurses help got up to use the facilities. A bit shaky, I made it in and began to sweat profusely, pulled the call bell and was placed back in bed by a 300lb male nurse. In the process my IV was damaged and jammed into my arm damaging the vein. With my BP 50/30 I was kept in for one more day. I tried to tell the doctor about my pain and discomfort, but he dismissed it ("you'll be ok, just move it and place heat on it"). I took his advice for the next two days and went back to work, but had to leave half way through the day, due to pain and swelling. Next, I went to my GP who said it was cellulitus. He gave me pain medications and a shot of antibiotics. This was Tuesday and he said come back on Friday. Thank God he called me the next day to follow up. My whole arm was red and inflamed and hurt badly. He asked me to come in immediately and, when I did, he had me admitted into the hospital. They scanned the arm and found 2 of the 3 veins filled with blood clots. I was hospitalised for 7 days and given blood thinners. One clot moved and the doctor. thought it had dissolved. However it had moved to my lung causing a pulmonary embolus. 8 days later I was discharged, supposedly to go back to work in 4 days. They prescribed Oxycontin and blood thinner for the next year. The pain in my chest is finally subsiding. However the pain in my left arm increased and sensations of burning pain, along with swelling and discoloration came along. The Pulmonologist suggested it was in my head and prescribed physical therapy. The PT helped with flexibility, but not the pain. I was referred on to the neurologist who prescribed neurontin 900mg a day. and confirmed it was RSD. I have not worked in 3 months and have been practising my exercises at home. I see some light at the end of the tunnel, but the swelling is great and at night even the pain medication doesn't help. The neurologist wants to do an emg. What will that show?
