Yes, there is no problem at all, but after you take it out make sure you keep it clean.
Cream
it does that before it heals. just like any other piercing.
yes. but not before the wound from the piercing heals.
Yes it is, it's a sign that the piercing is healing. yeah, its like a scab before a cut heals.
You should not make out until the piercing heals.
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.
If you wanna retire it, yes. Its best to retire it early :) If you mean to change it or something, no. Wait until its healed.
It's the tongues version of a scab it will ease off as the piercing heals, relax.
No. I had one too when my lip piercing was still healing. It's scar tissue and will go away as the piercing heals.
It depends on how fast your body heals, and how long you have had the piercing. The longer you have had the piercing, the longer it will take to close. This is true for all piercings.
The body is guarding the tissue while the piercing is healing, this toughening will ease off as the piercing heals. Be sure to stay on your aftercare routine.
Depends on the age of the piercing, the gauge, and just how your body heals. Most do close but they leave scars.
