Any known signs Cisplatin working on brain mets?

LovesLoons

I have over 20 small brain mets that were discovered in May. Had whole brain radiation daily for 3 weeks. I started Cisplatin Tuesday. Was told only 50% chance it would work and need to wait 3 weeks for scan.

I was just wondering if anyone could post any possible correlation between symptoms they had and if this led them to think the Cisplatin was working.

I know my oncologist would tell me if they had real links, but the waiting and wondering is going to drive me up a wall. 🙄😀 so anything..insight, guesses, etc. Are Welcome.

Right now the only possible connection I have of a tangible symptom is an eyebrow that feels numb. Not much to go on. 😂

Thanks!
