It is probably just a clogged pore- I would just watch it, keeping the area clean- if it changes in appearance or starts to hurt, itch, etc- have a doctor take a look at it.
1. You saying lump means under your skin. So nothing tropical can fix that.
2. You saying it is on the bikini line. I assume its in groin area... In another words. It might be a swollen lymph node !
If its not a pea sized lump or so underskin.. Please let me know
Girl. Whats new with you?? I have found a pea sized lump on my groin too. What did they tell you?
