Hello. I'm 57, 5'8", 350 Lbs., And Female. I Was

Hello. I'm 57, 5'8", 350 lbs., and female. I was recently treated for what doctors presumed was a blood clot in my lung. Couldn't get a CAT scan due to my size. I'm taking blood thinners for three months. My oxygen level was low in hospital, so I'm on oxygen. I feel as though I'm having an allergic reaction to the tubing in my nose.... runny nose, sneezing, burning feeling in nose and throat. Any solutions?
