Antiphospholipid syndrome (APS) is an autoimmune blood clotting disorder that can cause strokes and miscarriages...among other symptoms related to blood clots. It does not typically cause nerve related symptoms unless the nerve damage came from a stroke (and your symptoms are not common from a stroke). Therefore, I would think your buzzing/vibrations are not from APS.

Lupus affects internal organs and not so much nerves either. But that being said, both of these conditions (Lupus and APS) are autoimmune conditions and therefore can also be commonly associated with immune-mediated neuropathy (which DOES cause your buzzing/vibrations).

Just so you know, the simple presence of anticardiolipins (aCL) or Lupus anticoagulant alone does NOT give you the diagnosis of APS. The criteria for a diagnosis is to have 2 positive labs (at least 6 months apart) AND confirmation of a thrombotic event (like a stroke, DVT, PE, etc) or more then one miscarriage.

It sounds more like your symptoms are the result of a sensory neuropathy...likely immune based.
