MDS for 70yos

My dad lost conscious at home on 8/4, and admitted to the hospital and found out all his blood counts are low. He discharged about 8 days later without knowing what the reason is for him passed out. The doctor who discharged him told us to bring him back immediately if he feels any uncomfortable. Couple weeks ago he went back to the hospital due to rashes all his body but then developed into fever, and later on diagnosed MDS and finished his first round of chemo (7days) there. As of today, we meet most the team’s residents but barely the attendee. I’m not sure if we should seek for second opinion on his treatment since he already done his first round of chemo there. Any comments? My dad discharged couple days ago and will have appointments with a different hematologist a week later
