It does sound like this might be a keloid. As you probably know from the research you have done already, a keloid is an area of scar tissue that growth fast and excessively. The result is usually a firm to slightly soft, round raised area of tissue at the site of an old skin injury
, such as a piercing, burn, or cut.
The best thing to do would be to go see your primary care doctor
or a dermatologist
about this issue. They will be able to examine the area and confirm that this is a keloid. If it is not a keloid, they will be able to consider alternative possibilities, such as a cyst.
If this does turn out to be a keloid, your doctor will recommend potential treatments. For most simple keloids, the first type of treatment that will be tried is injected the area with a steroid medication to make the keloid shrink. In more complicated keloids, the area may need to be surgically removed, although this is tricky because care has to be taken to prevent the keloid from growing right back again.
Regardless, start by setting up a visit with your primary doctor or your dermatologist today!
