Patient: Bumps appeared about 10 days ago. They are small (1mm).
There’s no swelling in the groin, the pain is light and doesn’t change (no pain urinating) even when I touch the area. No risky behavior.

Doctor: Thanks for your feedback.
With the history and the picture you have provided, these look to be retention cysts of the skin glands.
These are usually self-limiting.
You may please keep them under observation; if they resolve well and good.
If they enlarge. may then need an active treatment.
If there is no lump in the groin the pain may be muscular.
I hope this answers your query and helps in decision making.
