A blood blister on your back can be a typical blister or be a sign of melanoma in its early stages. It therefore should be taken very seriously.
A typical blood blister forms when damage on the upper skin layers is sustained. Damaged blood vessels leak, resulting in formation of a bubble-like bump under the skin. Most blood blisters are raised above the skin. They appear red or dark. With time, usually about 2-3 weeks, they will heal even without specialized treatment.
Melanoma is a type of cancer, the deadliest of all skin cancers. If diagnosed early, it can be treated successfully. Advanced cases are too complicated to treat and in most cases fatal. Nodular melanoma can be taken for a blood blister on the back.
Difference between a blood blister on the back and melanoma
- Appears red or darkened
- Filled with fluid, mostly blood
- Mostly caused by friction. Other possible causes include; pinching, burns, allergic reaction, vitamins B12 & C deficiency, low platelets count, chicken pox
- Mostly raised above the skin and covered by an outer protective cover
- Painful upon touch
- Heals with time
- May break with continued assault
- Appears from nowhere
- Resembles a blood blister or a mole
- Gains mass rapidly
- Feels rough upon touch. It can also be dry, dark and scaly
- Is not uniformly pigmented
- Has no symmetrical halves
- Has irregular borders
If you notice a blood blister under the skin with such characteristics, it is likely going to be an early stage of melanoma. The blister grows more into the skin rather than outwards. It can for this reason be mistaken for a typical lesion, blister or mole for a long time. When touched, it will feel like a bump on the skin.
The best thing is to see your doctor. Medical attention is equally important if a blood blister keeps coming back. Treatment at home for such blood blisters on the back is very ill-advised.
How to treat a blood blister on back
If you are convinced that a blood blister on the back is not in any way a sign of nodular melanoma, you can choose to let it heal on its own, treat it at home or get medical attention.
Blood blisters heal faster when not popped and kept from further assault. You can for example consider dressing it with a bandage. Wearing loose clothes will help keep from repeated friction on the affected region. Also, make sure to keep it free from moist and wet conditions. Bathing after sweaty activities and applying some powder can help.
Some people decide to pop and drain blood blisters. In most cases, this option is not recommended. Popped blood blisters are more prone to bacterial infections. They also take longer to heal. Only pop a blood blister if it is large enough and showing signs of breaking in the long run. Before the minor surgery, ensure to collect the appropriate equipment and antiseptics. Don’t pop a blood blister on the penis, mouth or vaginal region.
In a clinic, the doctor may decide to drain the blood blister and dress it appropriately. If this is not necessary, some painkillers and antibacterial creams or ointments will be enough.
How to treat a blood blister that keeps coming back
If a blood blister keeps coming back, it is usually a symptom of a disease or condition. Such a blister should not be treated at home, let alone be ignored.
Boils and cysts, some of what causes blood blisters on the scrotum, may be responsible for recurrent blood blisters on back. Boils are caused by bacteria. Cysts on the other hand are advanced forms of acne. Both can be controlled with antibiotics and taking warm baths.
It is not often that a blood blister on the back will keep coming back if caused by skin trauma. Inside the mouth and on the hands and feet are the common body areas affected by blood blisters. One that keeps coming back on the back is highly unlikely to be something causual.
Let your doctor be the one to direct removal options if a blood blister keeps coming back.
Treatments for infected blood blister on the back
If a blood blister on the back breaks open, it will be prone to infection. The problem is that such a blister can break open and get infected even without your knowledge. Below are signs of an infected blood blister on the back:
- Continuously swelling
- Oozing pus
- Forming red streaks on surrounding areas
In most cases, these are signs of a bacterial infection. Such can be treated with antibiotics. Over the counter antibiotics such as zinc oxide creams and ointments can be applied. If the infection is severe, see your doctor for prescription antibiotic pills.
Infected blood blister should be kept clean to avoid further infection. Medicated soaps are good options in such cases. Also, keep the blister always dressed with a bandage. The bandage should be changed on daily basis.

If they are to be avoided, root causes such as skin trauma must be addressed. For medical conditions and diseases, the best you can do is get medical attention as soon as first symptoms are noticed.
Experts recommend keeping track of your moles. Adults can have as many as fifty moles. Most of them develop before adulthood. Keeping track of moles helps in identification of early melanoma signs. Melanoma blisters quickly show unique signs differing from those of normal moles.
