Ok. I have noticed something that has me a little concerned. I am a big guy. I admit to being overweight and I am trying to lose it but that is not the problem. I have a deep naval cavity. Here lately I have noticed a few times within my naval cavity dried blood. I clean it out and a few days later I see it again. Last night I cleaned it out and used a q-tip to see if it was maybe a sore or something. I think I may have like a sore in there but I was wondering if this could be symptoms of something else. I didnt know what section to look under.
