In brief: Rash bruise

My guess is that you are scratching the rash causing bleeding under the layer of skin which is the bruise.

Scratching can bruise but rashes can bruise without scratching too. Vasculitis / capillaritis have been discussed in my separate answer.

In brief: Deeper damage

There may be damage to the underlying blood vessels which os called vascultis.
This os a reaction pattern to drugs, or infection and my be associated to certain forms of arthritis. Ot is best ot see a dermatologist for a workup and possible biopsy fifths persists.

In brief: Bruise rash

Some rashes are called capillaritis.
An inflammation of the vessels causes leakage of blood cells out int the dermis which causes a bruise. These usually occur on the legs but other rashes, some virally induced or bacterial, and diseases such as rocky mountain sotted fever. See a doctor to evaluate your rash.
