(I have to do a chuckle here)....what kind of doc diagnoses vasculitis...A GOOD ONE! I would think a rheumatologist should be one of the first ones to think of it, however, that said, I have had the worst luck with rheumatologists.

A vascular doc is a likely probablility for diagnosising it, as it a good internal medicine doc. Vasculitis can be a symptom of another disease or the cause of other symptoms as a disease entity all of its own...

I believe Sjogren's manifests with vascultitis. There are many types of vasculitis, and even ones that affect just certain blood vessels, such as Temporal Arteritis or Giant Cell Arteritis. Usually sed rates are elevated with vasculitis, but other than that, I think it takes a 'sleuthing doctor' to dig deep enough to find it.

Vasculitis is autoimmune and I would think, (but I am not sure) that treating the Sjogren's would also address the vasculitis. Many connective tissue diseases (as well as many chronic diseases and their treatments cause blood vessels to become fragile.) Sjogren's has neuropathy and vasculitis as components....it may very well be that the attack of blood vessels by the immune system is the part of the pathology process of many of the collagen diseases. Blood vessels need a support system, 'collagen' and when that breaks down, the blood vessels can't get blood to the tissues, be they nerves, skin or other tissues.

Red spots on the tibial area can have a number of different causes and it seems you have several of them going on.

A solid Sjogren's diagnosis accounts for a lot of symptoms....it is a multisystem, multiorgan disease.
