Itchy Arm Fungus From Aqua Aerobics

I started Aquarobics at the YWCA.  I noticed after a while I started getting itchy only on the inside of my upper arms.  Its like a fungus.  My doctor gave me creams for it which do help a little.  But the spots almost look like ring worm.  I went on vaation for 2 weeks and it went away.  But as soon as I came back and started again? It's back.  What could be causing this.  It's soo itchy.  Is it the water? And why only there.  I am thinking when my arms rub back and forth on my swim suit during certain exercises might be the cause.  HELP

Hello,

I cannot confirm anything without examination but it can be fungal infection or ring worm. Most cases of ring worm respond to over-the-counter products, which contain any of several basic ingredients: miconazole, tolnaftate, terbinafine,ketaconazole and clotrimazole.You can consult a pharmacist and get any cream or lotion containing these ingredients. Also try keeping the area dry and wear cotton clothes.

If the symptoms persist then please consult a dermatologist and get the possibility of nummular dermatitis ruled out. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
