I'm swimming in a city pool, and have a minor case of psoriasis. It's just a patch of red skin on each knee, but scares people because it looks inflamed (they think infection).
Cover-up creams seem to create as much trouble as they correct. I'm thinking of a waterproof wrap, like an ace bandage. I have a full body suit but don't want to use it. (Besides, it's not for the pool, it's for diving.) Do they make arm or leg covers?
PS If you had a burn scar or a healing surgical wound you wanted to cover or protect, It'd be similar.
Me personally I wouldn't care what other people think. I have a huge gut that sags well below my belt line. Its not pretty either. Were both out there trying to improve your physical condition and if other people don't the way we look then that is their problem not ours. If you've gone to a doctor and there is nothing they can do then its all on how you handel it. Lemons or lemonade?
