Have you changed your soaps, lotions and/or detergents lately? Perhaps this is contact dermatitis? Have you stayed overnight in any hotels lately? There've been reports of bed bug infestations. Have you been outdoors? Perhaps this is due to poison oak or poison ivy. How are the insects in your area? Any possibility that these are mosquito or ant bites? Are the red bumps where you shave? Perhaps this is razor burn or folliculitis. If on the back of your arm, etc, you might have keratotis pilaris. More obviously, if you've taken antibiotics recently or added a new medication to your regimen, this might be a drug reaction (allergy). Best to go see your family physician. Good luck!
