Hello, I am a 21 year old boy, From last 2 to 3 years whenever I do sports, swimming, running or any exercises within ten minutes on my hand face and neck there becomes many numbers of small dots (blisters) (almost 10 to 15 dots (blisters) on face and 10 to 15 on neck) same dots as after bitten by a large mosquitoes or red ant and also feel little itch at that place, it remains for half an hour to one hour after that it becomes normal face and neck again, can this problem solved permanently?
