5 major causes for bumps on stretch marks
Stretch marks make the affected skin vulnerable to various bump-causing conditions.
The following skin conditions could be the reason behind the bump you see on your stretch marks.
Sometimes, we may develop stretch marks on areas prone to friction. These places become hot spots for developing boils too.
So, you may develop stretch marks on friction-prone areas like thighs, armpits, neck, breasts, or buttocks.
As the friction continues, the stretch mark gets tender, and staph bacteria on the skin cause the onset of a boil. You may then feel a bump on the stretch mark as the boil develops.
The hair follicle or oil gland around this stretch mark area gets infected with the bacteria, causing a boil to develop.
Over the years, boils have become more common since staphylococcus aureus bacteria became methicillin-resistant.
Treating it has become a challenge owing to the increasing development rates of boils among the people in the US and beyond.

- The bump starts to hurt
- Puss fills the bump with a few days
- It develops a white tip that bursts, letting out the contents

It’s advised not to pop or squeeze a boil. Squeezing or popping it may spread the bacteria to internal parts of your skin, thus spreading it internally.
Applying warm compressions with a clean cloth or cotton wool for an at-home remedy helps drain the boil.
The American academy of dermatology (AAD) advises compressing the boil area with a warm, clean cloth and covering it with gauze. Wearing loose clothes helps reduce friction in the affected areas.
You need to visit your doctor if the boil gives you a fever and other serious symptoms.
Standard treatment methods for severe boils include incisions, drainage, and ultra-sound for under-the-skin boils. You may be given oral antibiotics or admitted for intravenous antibiotics if the condition deems serious.
If the lump on your stretch mark appears purple, red, or brown, it could be dermatofibromas.
The bumps mostly appear on the arms and legs and could be stretch marks on these areas, and they feel like a hard bump on the skin.
- Sometimes painful
Small benign lumps may not require any treatment, and a surgeon may remove large ones via surgical excision and cryotherapy.
The lump could result from folliculitis if you have stretch marks around hairy areas.
With folliculitis, the bump on your stretch mark causes inflammation on the hairy body parts like the armpits and inner thigh region.
These lumps result from an infection or physical or chemical irritation.
These lumps affect diabetic, obese, or immune-compromised people more than the general public.
- Red lump on the armpits or other hairy parts of the body

Sometimes, your doctor may prescribe antifungal medication. If the doctor finds a cause, try eliminating it, especially if dietary.
4. Keratosis Pilaris
Keratosis Pilaris occurs mostly in winter when the humidity gets low, and the skin dries.
These conditions may result in bump-like pimples on your stretch marks.

The bumps appear mostly in people below 30 years. Once you reach 30 years, they often stop occurring, especially during winter.
Use moisturizing cream during winter to avoid extreme skin dryness. Medicated creams with alpha-hydroxy acids or urea prove helpful for severe conditions.
If you notice a red, thick, dome-shaped bump on your stretch mark, it could be Keratoacanthoma.
Keratoacanthoma bumps appear with craters at the center, resulting from the abnormal growth of hair follicles.

Also, they may occur after exposure to UV rays.

Do I have a PUPPP rash?
Pruritic urticarial papules and plaques of pregnancy (PUPPP) occur as an itchy rash on the tummy during pregnancy.
Since the stomach develops stretch marks during pregnancy, the rash may cause bumps on them. The hive-like itchy bumps disappear once the baby is born.
It may spread to other parts of your body but won’t harm you or the unborn baby. Visit your doctor to get some relief medication to lessen the itching.
Should you squeeze a boil?
No, squeezing a boil may cause the infection to spread under the skin to other internal organs.
How do I know if it’s a boil or a cyst?
Although boils and cysts may look alike, cysts don’t spread, while boils may spread due to bacteria or fungi. If the lump extends to another area, then it’s a boil.
What does PUPPP rash look like?
The bumps due to PUPPS may be small, itchy, red, and raised. They look like small and pink pimple-like spots in the stretch marks, resembling hives.
If not tended to in time, it may come together and form large, red, plaque-like areas.
