Re: two lumps on inner thigh
Unless you are at risk for an STD, it sounds like they may just be pimples. I would suggest keeping the area clean and dry. Make sure to completely wash the area in the shower and then keep it dry during the day. If you get really sweaty, make sure to clean and dry the area and then change into a clean pair of underwear. You may also want to apply some antibiotic ointment to help them heal.
In the event that they get worse or do not go away, you should see a doctor. It is sometimes possible to pickup a bacteria that over the counter ointments will not treat. When that happens, a doctor needs to give you something stronger.
Good luck to you.
