Well you can always go and get your doctor to examine the area and give you a diagnoses.
But, I am confident that this is what you are experiencing. I have suffered with it and under my breasts too.
Because the area is warm and damp this is where the fungus likes to thrive. We already have it on our skin, but if the conditions are right, the fungus gets out of hand, hence the soreness and redness and sometimes it will feel itchy as well.
An antifungal cream is the correct cream to use for this. If you prefer home remedies, then you can apply natural live yogurt to it. You will have to do this, as with the antifungal cream for a few days after the symtoms have gone.
Hydrocortisone creams would thin the skin, but antifungal creams are not quite the same. But still need to be applied sparingly and as directed on the packet.
Of course, you do not have to do anything at all, and just suffer the soreness. Usually if left untreated it does get much worse and drags on for ages.
But you do have "visible indicators". You have already said that the area is sore and red.
If you do not wish to be seen by the doctor, pharmacists can also give you advice.
You can also pick up the fungus through unprotected sex and from using antibiotics. It is also quite common for people who are overweight, are glucose intolerant and those with diabetes if the sugar level in the body is not controlled.
Best wishes.
Thanks for the response!
Are you sure it's likely to be a fungal problem, given there are no visible indicators? And if it isn't, could the antifungal cream have any negative effects?
Thanks again!
What you have is a fungal problem.
Because we sweat in that area and it is warm this is the perfect conditions for Thrush to thrive.
You can either go and see your doctor to get an antifungal cream on prescription or buy one over the counter at the pharmacy. Canesten can be bought over the counter in the UK, but you may have different products available where you live. Your pharmacist will be able to advise you.
Keep the area clean and dry. Don't use soaps and harsh products, or bubble baths or shower gels. Wear cotton underwear and do not wear tight clothing.
As a home remedy before you get any antifungal cream, you can apply live natural yogurt to the area too.
Best wishes
