I am Dr. Sunil, General Surgeon
from India. After going through your query I would like to tell you that the hygiene of the perineum
, the area covered by the undergarments is of prime importance to protect oneself from skin, genital, urinary and lower gastrointestinal infections. Since you had used your shorts continuously even after getting it wet, there are chances of fungal or bacterial infections in the perineum. The area is humid and mildly anaerobic (lack of oxygen
) once the shorts are wet which is very good condition for the fungus to grow. Hence I would advice you to maintain a good hygiene change your shorts regularly. As for the current symptom of yours drink plenty of water and fluids so that your urine output is more than 3 litres everyday. Get yourself a routine microscopic examination of your urine done to look for any infection.
Feel free to discuss further, and hoping for your speedy recovery.
