as much as i would like to help you with your diagnostic dilemma it is not possible to blindly determine the nature of yoru hand lump/blisters based solely on a description. this requires a hands-on medical examination -- obviously not something that can be accomplished over the internet. there is really a high probability that this is an infection; one that may require antibiotics so i would suggest that you seek medical evaluation as soon as you can.
i have one hard lump with white pus and a few tiny blisters at waistline. herpes or abscess or something else? . i have not had sex in three weeks. i did wear a condom. it was with someone i have never known. i work and for the most part live in the middle east where it is currently 100 degrees in rough living conditions. i usually sleep naked last night i slept with nylon type of boxer briefs and woke up with the red hard lump and had a few tiny blisters. i did not have itching or tingling prior to and i have not had painful urination. it is approx 2- 2. 5 inches below the navel where my waist band is.
