Since I was 12, I have suffered from intense itching on my legs and sometimes on my arms at certain times of the year. Usually this happens during the summer, but recently it's occurred during the fall. It is most severe after showering, and lasts for about 30 minutes. I itch after long hikes and when I'm just sitting around the house. I've even been awakened at night by the intense itching.
Scratching seems to make the itching worse.
I've never had any rashes or bumps. I've tried using no soap and cool, hot, lukewarm, long, and short showers, but nothing seems to make a difference. I've seen two doctors. One said I was allergic to temperature changes, but I rarely itch in the winter, and it doesn't happen every summer. I take Claritin and Allegra during these itching spells, but they don't help.
