Suggest remedy for redness in the testicles and anus
Welcome to Healthcare Magic.
I read carefully your query.
Because this area can be very humid ,fungal infections in this area are very common. This can cause a persistent irritation.
You need to keep this area clean and dry using a powder.Wear cotton loose underwear.
I would suggest to apply an antifungal cream like Clotrimazole twice a day for 2 weeks.
If the discomfort doesn't seem to improve you may need to try applying some over the counter 1% hydrocortisone cream twice a day for 1 week.
If the symptoms don't improve ,you may need to see a doctor because it might be a fungal infection that need a stronger prescription antifungal treatment or it might be chronic dermatitis that require a stronger steroid cream to clear up.
Hope it helps.
Let me know if you need further help.
