I am experiencing extreme fatigue/shortness of breath and heat sensitivity although my thyroid panel was normal. I am taking a calcium channel blocker for blood pressure Celexa for anxiety and Symbicort and a rescue inhaler as needed. I feel that my GP brushed me off when I went over my symptoms with him and I know something is not right but can t seem to get him to hear me. I had a heart cath several years back that showed minimal pulmonary hypertension and am a little concerned that this may be some of my problem. I suppose I just need some direction as to which type physician to go to for the proper treatment of my health problem. I am otherwise a healthy 63 year old female 5 7.5 , 181 lbs who up until recently (12 months are so) have been very active now I get tired and winded just walking 20 feet or so. Thank you for any advice you can give me.
