I was in the hospital for a week in January of this year and since then have been on oxygen at home sometimes, and usually need it if going out to the store, etc. I was never on it before. Since coming home, I have edema throughout my body, especially on extremities, like my legs feet arms and hands (fingers). I NEVER had edema before going to the hospital. I am taking Lasix 20mg daily and it doesn’t seem to help very much. The swelling is often painful. I saw a pulmonologist last week who swears the root cause is sleep apnea and wants to do a sleep apnea take home test. It sounds kind of off to me because I do rarely snore, I don’t have times in the night when I stop breathing or gasp for air during sleep. I sometimes I do have daytime sleepiness and falling asleep. I don’t understand how any of this could be related to the awful edema I’m now experiencing.
