HI. The hard lump you described looks to be due to an abscess and may be related to the heat rash you had. Probably you scratched the area during sleep, and got infected. Another possibility is of a perineal abscess which may be a part of an impending fistula in ANO. I would advise you to consult a General Surgeon to examine, determine what it is and to give you a prescription of an antibiotic and anti-inflammatory medicines. If it does not open up, you may need a surgery and have to watch for a recurrence.
