Pulmonary Embolism symptoms I confused with Chemo side effects

Just a quick post to flag up a mistake I made - in case others do the same.

I was on adjuvent chemo, cistaplin and vinorelbine, planned for 4 cycles, 21 days each.

For two or three weeks I had a tightness in the chest and was increasingly more out of puff. This I guess over cycles 2 and 3. But otherwise I was functioning normally, within the constraints of the usual minor chemo side effects!

I put this down to the chemo reducing my red blood cells in my lungs and so making it harder to breathe when i exerted myself. The worst effect was when I bent down to load/unload the washing machine. I would see stars and came close to feinting I guess, but a few deep breaths and I was OK. I wrongly thought this was the lack of platelets in the blood, a minor chemo effect.

I had a CT scan, with enhancement, as planned after the third cycle of chemo. This showed up a large blood clot on my lungs. A pulmonary embolism. PE, as they are called now. I was rushed from the Diagnostic Centre to the nearby hospital cancer centre that is treating me. 

So I was very lucky with the timing of the CT scan. I was immediately given blood thinners. I will stay on these for the foreseeable as i am due to go on Tagresso soon and apparently this has a similar increased risk of a PE to that of chemo. Cycle 4 of the chemo was cancelled. 

Hopefully, me not realising one of the signs of PE was just my mistake.
