Hi and welcome to the forum.
Treatment side effects vary enormously.
I think that the most common side effects are:
– Fatigue
– Sleeplessness after taking dexamethazone
– Brain fog
– Gastrointestinal issues (diarrhoea and/or constipation).
I had all those (roughly in order of frequency and severity).
I personally had an erratic heartbeat a few times (but I already had a dodgy heart anyway).
My more important message is: this too shall pass. I was diagnosed in 2022, had Dara-VRD, but no transplant (which could have put a strain on my heart). I am still in remission: just back from a tough gym workout as I type this!
Please let us know if you have any questions.
All the best.
