In September, I underwent umbilical hernia repair surgery. In the recovery room, during extubation, my airway collapsed and I spent 24 hours in ICU. Approximately three months later, my left hand and arm swelled enormously. A trip to the ER and IV steriods, antibiotics and Zantac started bringing the swelling down (hand and arm returned to normal after a day or so). Two weeks later, I was taken to ER (by ambulance) when my airway swelled shut. IV steriods and epinephrine eventually started to bring the swelling down after several hours. I was ordered to stop taking my LISINOPRIL (40mg). I continued to experience large painful red welts all over my body for the next few weeks. I started taking prednisone, benedryl, zyrtec, and zantac whenever I started having further outbreaks. My doctor started me back on my LISINOPRIL due to my very high blood pressure readings. My doctor also gave me a shot of prednisone. I had a week of bliss with no episodes. After that I experienced severe facial swelling on three separate occasions. I used epi-pen injections but still had to go to the ER. ER doctors used same protocol as before. A Feb 8 CAT SCAN showed a mass in my throat that was displacing my trachea. I am again off the LISINOPRIL and MYCARDIS HCT. My C1 and C4 levels are normal. I am now waiting on results from an extended IG cap blood test. Within the past few days, I have also started experiencing sharp, aching, short-lived pains in my elbows, forearms, and neck/shoulder area. Today my left ankle is swelling, the back of my left knee is swelling as well, and very painful. HELP!!!!! ***Since writing this 2 days ago, my left leg has continued to swell up through my calf. It feels warm to the touch and hard. Lots of pain.
