Blister on shoulder with two black dots

Should I be concerned about a small spot that has grown to eraser sized recently? It looks like a small blister with two tiny black dots. Thanks.

Hi,

When did you first notice it?

Do you have any pain or discomfort?

Does it itch or burn?

Is it like a bump?

Does it have a discharge of blood or pus?

It is difficult to answer what this could be the cause of this without a proper examination. However, what may be done is to resist touching or pinching it so that if an infectious focus is present, it does not spread.

Please visit your doctor and let us know his/her views.

Best regards.

Thank you, Dr. Bhumika. I made an appt. but it will be in a few weeks. Today the raised blister type spot, has 3 dots that are a little larger and appear brown. They  are placed symmetrically,  like a triangle. I will be in Florida sun for the next 5 days and wonder if I should cover up the spot and if this new info. helps you to dismiss it.
Thanks,
Maureen
