pulmonary hypertension
"Letaris had some side effects that were rather unpleasant but well worth it. I can go up a flight of stairs and usually not lose my breath. The difference between how I felt before and then after starting this med was like night and day. Truly amazing. My oxygen saturation was 98-99% in my 6 min walking test vs. 92% before Letaris. Downside is these horrible red splotches all over my chest that do not go away. (I think they are broken capillaries)."
