Hi, I m a 23yr old man, and I m having this soft, dark red coloured lump on my lower buttocks (the cheeck itself). I have no known allergies, nor a history of severe acne or other related conditions. It is rather painful and annoying, and especially painful when pressure is applied. This makes it very hard to sit on as well. It feels very soft like it is filled with pus, it has no hard part like a cyst would have a pea-like head. This lump comes for a few days to a week then goes away for a while, only to return at a given point. It can occur on both the left and the right cheeck. I doubt it be some hygiƫne problem, as I ve always paid attention to it, especially now since these lumps have been appearing. Could this be something like an ingrown hair? Most likely not a pimple that has gone crazy, as I would have noticed the pimple itself. Would you suggest to just wait until it disappears again as it has done before? Thanks
