Pictures Of Blisters On Gums On My Arm Little Bubbles Of Blood ( Not Blisters) Are Starting To Pop Out In 1 Spot?

On my arm little bubbles of blood ( not blisters) are starting to pop out in 1 spot? - pictures of blisters on gums

I noticed that a growing number of freckles or moles and in me lately. I'm worried, of course, skin cancer. I was looking for photos, but only care about myself in hypochondriasis. In my arms in a concentrated area of small bubbles in the blood in different sizes. I have no idea what they are is that it should not be. If anyone has any idea what they let me know!
