What you can do about your wetsuit.....
Sounds like you have allergy issues and something in the wetsuit material is making it worse.
Chances are it's something new is some stupid new feature like the new inside surface.
The fact that Hyperflex responded quickly, but could not/ would not tell you what it's made of is
something to worry about. Sounds to me like they are hiding something. They have to know what the hell their products are made out of.
I would return the wetsuit and go with soothing better.... and best keep it less fancy....
One wetsuit you may want to consider is getting is a Patagonia. They are expensive, but use very good materials and even obtain their rubber base for a renewable plant source rather than synthetic.
Another thing that my help is using a thick thermal rash guard. I use one made by O'Niell.
They tell you what it is made of too. It's like a light fleece. Keeps you warm and dry. Get it on the small size so it really clings well to your body. They also make shorts. Flat lock stitching so no irritation there.
Also best way to look after your wetsuit that is used in fresh water is to give it a salt water soak
after your session. Pretty much anything mold,fungal or bacterial that lives in fresh water will croak in salt water. Lightly runs it off so some salt remains and dry the wetsuit well. Best to use a very big wide wetsuit hanger with a built in fan. Dry your suit quick that way. Then when you use it again wet it with warm slaty water to soften it up so you don't stress it out when getting it on.
One other thing that helped a friend of mine is a Muscle balm. He had sore knees so I recommended Shane's Miracle Muscle Balm. It's a really nice natural heating balm. It's in a natal wax base. It was great for his knees and had the benefit of getting rid of dashing he had on the back of his knees. I love the stuff and use it on my left knee that was broken when a giant sled crashed into me while I was in a gully on skis going up a ski lift as a kid. Never been the same after that accident. I'm not sure how it's working for the rash he had, but it could be a combination of the hot spices see in the blame and the lubricating qualities of the wax. Will also keep water off the skin where the waxy blame is.
