confused... allergies symptoms or?

[paris p]

I have many tiny pinhead sized red bumps on my whole body. I 1st starting seeing them below my knee when i tried to shave my legs. They feel hard to the touch, raised and if I scratched them a hard white substance came out. Then they would heal but leave a red dot on my leg where they were. Now I am seeing that they are above my knees, still reddish and a lil pink. They are not painful at all.When I broke out with the ones on my thighs, I also had some on my chest, my stomach and back. My dr assured me that i didnt have herp, and that he thinks i am suffering from allergies being light skinned. I didnt have any of the symptoms of hsv. The bumps usually disappear in a day, day and a half. The bumps on my thighs when i scratch them, all that comes off/out of them is just dead skin. Am I just over reacting or freaking out over my body's allergies to certain things i wear/come in contact with? (plz dont respond if you are going to say I dont know go to the doctor.) Thank you
