I have been suffering for the last 2 months about this problem, it started when I stopped taking
Accutane; it seems that after my skin is exposed to water, such as swimming or bathing, my skin starts to have this prickly, itchy, burning sensation only on my arms and legs that lasts from 10 minutes to 20 minutes. The oddest thing is that I dont see any visible rash nor redness or any signs of irritation.
