blood clots after first chemo - 1269942

Hi, haven't posted a while. My husbans chemo delayed, had surgery, radiation and was awaiting trial biopsy. Etc. Long story short he started actually 6 months! But minimal progression in lungs. But after first cis/pem treatment he got chest pain day 5, After getting him reviewed at local hosp he had multiple blood clots in lungs and vasculitus? (may have that bit wrong). Prior to him starting chemo during the tests for immuno trial radiologist said that most of what had been considered to be metastasis in lungs she thought was cysts and scar tissue. Main mass 3.5 cm adeno, and nodules, considered to be lung mets. He had only had denosumab prior for bone met to hip, for which he had femural pin and radiation.

The radiologist and oncologist at local hospital said his scans are very difficult to interpret. But why so many blood clots so soon after treatment. Remember he had none forn6 months prior treatment. What are the cysts and scar tissue there before? Few other things odd they say they cant explain. What could that be? Could it be another underlying lung disease (yes ive asked they say they don't know). Should I push it or just let them keep treating and not keep asking. The hospital who told us of blood clots said looking at his scans he should be in intensive care but he's seemingly ' bearing it all amazingly well'. He got blood thinners and home next day. Apparently he had high dose cisplatin with the pemetrexed. Would it be rude to ask for a specialist in interstitial lung diseases to look at his scans. Would oncology already have done that, or maybe it doesnt matter if he has stage iv lung cancer. I dont know. I feel like im talking to myself. Am I being irrational to worry about these seeming anomalies? Maybe this is all perfectly normal? Anyone thoughts, experience to offer?

Kind regards
