If its an old piercing its most likely scar tissue, if its a new piercing its most likely getting infected and there is pus in the bump.
A hood piercing is where you pierce the skin which is above (& slightly covering) the clitoris. There are vertical as well as horizontal options.It's a female genital piercing through the clitoral hood surrounding the clitoris. There are two main types of hood piercing, the vertical clitoral hood piercing and the horizontal clitoral hood piercing. As the name indicates, the difference is in the direction the piercing is oriented in the skin above the clitoris. Neither of these piercings penetrates the clitoris itself.
A bump near a new piercing is most likely a Keloid. A Keloid is basically a scar cause by condensed scar tissue from the piercing. I have a few due to piercings, and I've noticed that as time goes on, the Keloids become less noticeable and irritating. It's very common and nothing to worry about. However, if it begins to enlarge or hurt really bad, seek medical attention as you may have an infection.
In your clitoral hood :]
No Having any form of lump or bump next to a closed piercing indicates there is some form of issue with the piercing. This also depends on how long the jewellery has been out of the piercing and how long you had the piercing before removing the jewellery. If you develop any pain or discomfort seek the assistance of your doctor.
A bump around your dimple piercing is the body guarding the piercing, the surrounding tissue toughens as the piercing heals. This will ease off as the piercing heals, ensure you are rinsing the piercing daily under running water (best done in the shower after shampoo and conditioner as these tend to irritate the piercing). Should you have serious concerns contact your body piercer and let him/her have a look at it.
Is it okay to bleed out from the bump near by my ureter?
Its probably Hypertrophic scarring. which is very common wit any cartilage piercing. Go to walmart o a drugstore and get a bottle of Tea Tree Oil. It's like $5 for at least a years supply. Just use a q-tip and dab a bit on the bump every day after you clean your piercing in the morning. The oil will dry up the bump and it'll flake off until its gone. Don't overload on the oil because it'll dry the piercing out. Try your best to get it on the bump and not on or in the piercing.
try to put tee tree oil on it
Use a q-tip and just dab the bump with the oil. Use it after you clean your piercing. I usually apply it twice a day but if that's too harsh for your piercing, only use it once a day. You don't want it to go inside the piercing, just on the bump. The oil will dry out the bump and it'll start flaking off in layers. If the tea tree oil doesn't affect it, it could be the jewelry. Especially if its a ring and gets hit often.
Mine didn't. But I've seen others have a bump on their nose from the piercing. But of course I always do my own piercings.
Yes it means that the piercing is not healed correctly and there is a buildup of matter inside the piercing. See your doctor.
