question: Hi I am a 22 year old Asian woman and I have noticed that I am becoming increasingly short of breath after doing small tasks such as walking around the house, showering, going up and down the stairs. I am also pretty sure that I have a murmur in my pulmonary area (it sounds systolic but I m not 100% sure. I am still just a medical student). I also get palpitations infrequently, but when I do it is usually when I am at rest not stressed or doing anything in particular. The most bothersome thing is the shortness of breath. it does get relieved when I sit and rest for a bit though. I have noticed it for a while and it is not very severe but it is definitely more noticeable now. I am just not sure what to make of all this. any help would be appreciated
