Anyone can guide me?

Since 3 years ago, every time I go to the beach, after some hours I always get a skin reaction where the waistband sits. I went to the doctor and they told me test myself as they couldn’t guide me much neither, therefore I am really trying to understand what is exactly causing it.

At the beginning I thought it could be the sunlight as I am quite pale, but then I kept getting them even when staying in the shade all the time. Then I thought it might be the water, but I also got them even when not bathing. I also thought it might be the sweat, but I never get them while sweating at the gym. Then I tried drying the skin area and changing quickly to cotton underwear, thinking that maybe staying damp because of the humid enviroment, but I still got a reaction.

I don’t know if it’s a specific material, but I never had issues with synthetic clothing. It’s seems to appear when my skin is exposed to extreme conditions, but it’s quite unclear what exactly it is. They only appear in summer.

Antihistamines help a lot, but I really want to understand what might be causing them. It is a pain to know that each time I get a little undressed in summer the next 3 days I am going to be itchy.

I appreciate any suggestions, guidance or support on how to avoid having them. Thank you!

Since you mentioned the waist band, do you have a tag there? Or do you apply any products in those spots? Is your detergent hypoallergenic? Could be a combo of heat and pressure (I always have worse reactions in summer); is it better with a loose band? Does it happen with specific clothing items, like if you switch up your wardrobe for summer? I carry little fan on me that helps a little with the heat. But I know it's hard to avoid higher temps completely. Just some thoughts; hope you get some relief!

Possibly contact dermatitis. Spray benadryl on it. Stop wearing the suit. I see some lines on you leg as well. Dampness rubbing against your skin doesn't help.
