Welcome here on Health Care Magic Dot Com.
I am very much concern of your problem.
I think I will certainly able to help you out of this condition.
In my view the bumps you have must be due to insect bites
in your bed or outdoor.
Usually they donot need any treatment.
They usually disappear within 10days.
You can use soothing lotion or antiallergic crea at places.
You can use antiallergic tablet for itching.
I suggest you if these are not disappearing after 10 days than visit to your gp.
