Large Red Blood Blisters on Arm Pits and Inner Thighs

I've been treated for infections (Staph) and treated for psoriasis. I get these blood blisters from time time under my armpits and in my inner thighs. I've attached photos.

What could it be??? They hurt and leave permanent scars!

Hello,
From the symptoms the possibilities are of boils. Boil on buttocks is usually due to plugged sweat glands that become infected or by an ingrown hair.

Apply warm compresses on the boil and keep the area clean. Drainage of the boil is done only when it becomes soft and forms a head. Take some over the counter pain reliever and consult a doctor for examination and antibiotics prescription. If there are recurrent boils, then please get your blood sugar levels estimated.

I hope it helps. Take care and regards.
