Hello. I donated blood 4 days back. After donating blood, nurse applied band aid on the area where needle was inserted. I forgot to remove band aid, and got it away after 2 days. What i found is that the band aid area got red rashes . Although i don t have pain and itching over thr. But still i am confused, is it something serious. I consulted medical store guy, he replied that it will get better by time. No need to worry, though he enquired about the pain in the area. But when i told i do not have such problem, then he told relax and it will get better by itself Please tell what should i do?
