Rash, pimples, sores and other skin ruptures often appear and disappear. Any problems can cause pain and blisters on the back, from burns to herpes zoster. Friction can also cause irritation areas and blisters; wearing sports equipment, such as shoulder pads or other clothing that rubs the skin, can cause pain and blisters. If you have blisters, talk to your doctor, especially if there is redness, pus or swelling in the area.
Friction
If you wear clothes or equipment that fits snugly or slips back you can make a blisters on site. Normally, the stimulated area will initially appear red. If the stimulation continues, the top layer of the skin begins to separate from the underlying layer. The generation of fluid between the acc layers produces blisters. While most clothes won't rub on your back, sports equipment such as football mats can, especially if not properly installed. Pay attention to areas that are red or sore, indicating that your device is not correct. Once you stop stimulating in the area, the blisters usually resolve within a few days. If your area becomes redder, call your doctor if you have a fever or other signs of infection.
Herpes zoster
If you have had chickenpox in the past, you carry herpes zoster virus to sleep in your tissues. In the later stages of life, stress or trauma can reactivate the virus, causing herpes zoster. According to the US Centers for Disease Control and Prevention, nearly 33% of Americans have herpes zoster at some point; nearly half of them are over 60 years old when they broke out. Herpes zoster causes small vesic sores to appear along the nerve pathway, often forming streaks on the left or right side of the body, including the back. Like chickenpox, shingles cause fluid-filled blisters to rupture and scar.
Boils
Staphylococcal infection of the skin can cause fur, better known as bo. Infections that occur around the hair follicles, boiling usually begins when the bacteria enters the skin, such as a scratch or other injury. This area forms a pus-filled pain, a rosy blister-like structure. Use a warm compress to help boil and release pus. In some cases, your doctor may boil and expel it. Antibiotics may be needed in some cases.
dermatitis her petiformis
chronic dermatitis herpes causes extreme itching and red areas of the skinUsually on the back. You may feel a burning sensation in the area before blisters appear. Each outbreak lasts for a week or two to heal. This disease is caused by gluten allergy, which is more common in men and people of northern European descent. According to the American Osteopathic Institute of Dermatology, 10% to 20% of people with this disease do have remission. A gluten-free diet can cure the disease, but the lesion can take months to stop.
