I get something similiar, but I am not on meds yet (will ne Dec. 3 once my results come in).
My "bruises" are small, like the size of a pencil eraser. They do not hurt, so I know that are not bruises from external reasons.
My doctor suspects a blood vessel coagulation problem. He also suspects this due to white patches on my skin that are not due to pigment loss. He had a name for it and I don't remember what he called it.
He ordered many tests for coagulopathies. He is a Lyme specialist, but he has special interest in what these infections do to our vascular system. He believes this is the root cause of the manifestations of Lyme and the co-infections.
Below his name it says- Internist, Rheumatologist and Inflammatory Vascular Disease Specialist.
Hope that helps. I, too, wondered if others had these kind of bruises.
