Sounds like it may be a granuloma, have a look at the bump thread to help. If it is that then keeping it dry can help. Make sure the bar isn't too long and is made of implant grade titanium.
Hi 2 months is very early days, they can take a good 6-12 months to settle fully. Have a read of the bump thread, it's very common.
Not until they're fully healed which can be anything from 9-12 months or more unless it's an essential downsize.
