Those probably aren't actually pimples, they just look like them. Those are actually caused by dry skin flakes building up around your pores. Try putting some moisturizer on your limbs before you go to sleep for the night. ..... What you're describing sounds like keratosis pilaris. Keratosis pilaris (ker-uh-TO-sis pil-AIR-is) is a common skin condition that causes rough patches and small, acne-like bumps, usually on the arms and thighs. Though you may not like the sandpaper-like appearance of your skin, keratosis pilaris isn't serious and doesn't have long-term health implications. Keratosis pilaris can be frustrating because it's difficult to treat. Prescription medications and self-care measures can improve the appearance of your skin. Note: regular exfoliation and use of body lotions does help lessen the appearance. Keratosis pilaris results from the buildup of keratin - a hard protein that protects your skin from harmful substances and infection. The keratin forms a scaly plug that blocks the opening of the hair follicle. Usually many plugs form, causing patches of rough, bumpy skin.

It sounds like you may have 2 problems. Your back has oil glands especially your upper back. It's most likely "backne" acne on your back. Have someone use a cotton ball soaked with any of the following, benzoyl peroxide, salicylic acid, glycolic acid or alpha hydroxy acids sipped on your clean back. Available OTC or by presciption strength. If that fails a retinoid like Differin or Retina-A by presciption. Keep area clean and hair clean & off your back until clear. On your upper arms you may have blocked hair follicles called folliculitis. Try exfoliating with a scrub to free up the hairs. Keep area clean & dry. Tight shirts make it worse by pushing hair back under skin. Clean area with hibecleans, available at drugstores. If that fails, you may need a Dr's Rx for an antibiotic such as minocycline which kills the Staph found on skin. The hair follicles can get infected from the inflamation. Inflamation causes the hair to become plugged. If you pick you can get dark pigmented scars so hands offs! Good Luck!
