Shortness of breath and heavy feeling in the chest area, indigest...

Shortness of breath and heavy feeling in the chest area, indigestion has increased and a feeling of tiredness and my heart still feels like its coming out of my chest while taking toprol XL 25mg for 3weeks. My MD feels it might be anxiety, but i think its from the toprol. I go back to the MD tomorrow. Prior to my hysterectomy (partial-still have tubes), i did not have high BP and I think my BP is not really high, now. Prior to surgery it was normally anywhere from 115-120/70-80. After the HYS, I went to the ER for shortness of breath and pounding heartbeat. It was found that I had a DVT in my right leg, so they started me on Lovenox injections, which was discontinued and Coumadin 6mg. At the same time I was given toprol 25mg daily due to pounding heartbeat (but still was in range under 100) and Davarcet for pain. I stopped the Darvecet after 2 days of being dc'd. It worked for maybe a couple of day after but by the weekend I was calling the MD again due to shortness of breath abd pounding heartbeat. An ultrasound, ekg, echo of my heart and nothing was taken of while I was in the hospital for 2 weeks. Help! anybody experiencing the same feeling?
