I have had a reddening of both lower legs, increased swelling and increased numbness of both feet and hands. I was dx with COPD about 3 yrs ago and of course stopped smoking that very day I went to the er with SOB. I also have asthma and have been on Breo and Spiriva. Thinking the swelling was a result from a recent L knee scope, my Dr put me on Dyazide. With a sudden lack of activity I have gained close to 100# since 2010 when I had my first knee scope, ORIF of L ankle, ORIF of R rotator cuff and Dec L knee scope which soon will need a repeat surg. Due to atypical chest pain, I just had a stress (chemical and tredmil) test and thee result was normal. So, now I am thinking either CHF or Pulmonary Hypertension. What test should I ask my Dr. to do next to rule these out or make it conclusive Dx? I am 62 no family hx / adopted.
