Herceptin questions

[Teal55]

I finished Herceptin/Perjecta (18 rounds total) I'm in a clinical trial. I finished July 2016.
It sounds like you may want to get an ecocardiogram. I have been having one every 3 months. I have had some difficulty as well and I exercise and walk (5 miles) but it doesn't seem to change anything for me. I'm wondering if it's a horrible side effect. I too had chemo and radiation. I'm wondering if my tightness in check and sometimes difficulty breathing might be a radiation side effect? We have been through so much it's hard to know what's causing what. Are you also on Aromatase inhibitors? I'm struggling with those now and stopped until I get a second opinion. I would let your doctor know about your winded experience. Doesn't sound good. Good luck!
