Hi Marcy, yes i am, all of a sudden. I find it difficult to let enough air in. I have been working out regularly so that is not the reason.My last scan was stable but my imune system is not completely back online so i am wondering if i have not contracted something? I contacted my oncologist just to be sure..It is possible that it is because you have not worked out for a couple of months. if so it should get better over time...

Nothing is good I think.

Could you be anemic?

Thanks everyone for your input...I contacted my oncologist, and i will get an X-ray tomorrow. She does not know what it could be at this point (i had a scan a month ago, and all was stable. TO be followed...🙏🏻

There are many possibilities, Brigitte. In my case, I had and still have C.O.P.D. I had SBRT for my lung tumor, and now that tumor is scarred and no longer functions in taking a breath. In my case, perhaps others too, it's possible my heart simply can't keep up with the demand when I exercise, thus oxygen doesn't get where it should be. If you have ANY doubts, have it thoroughly checked out. :-)
