User blog comment:Meganoide/Doc Q and his fatal desease/@comment-1595565-20101014032201

I'm going to have to disagree. Roger showed physical pain due to his disease. Doc Q, despite the fact he drools blood like it's saliva and coughs more often than he actually breathes, has never actually shown physical pain like that. Also, since he seems constantly sick, it would only make sense that he would need constant medicine, yet he was never seen taking anything. Crocus was able to alleviate Roger's pain to the point that he could fight in his prime against Shiki. The most active I've seen him was when he stabbed Whitebeard with his scythe. It's hard to measure his skill as a doctor since he has never been seen treating anyone. Interesting theory though.
