Pins & Needles: Old Lyme, Dengue, Back or MS?

[meemsy2]

Hi.  49 y/o formerly very active female with daily sharp pins & needles in face, left arm & leg.  No doctor now, but MRI in March '07 showed 3mm "vascular malformation" in brain.  (Idiot doctors missed it the first two MRI's then sheepishly called 10 days later to tell me.)  Also, fatigue starting mid-afternoon, dizziness and lack of appetite.  Have lower back pain too, so not sure if tingling & dizziness are from the lyme disease I think I had three years ago, the Dengue fever I had a year and and half ago, a possible bulging disc (which a doctor denied, but two physical therapists were sure I had) or the 3mm brain thing.  Any thoughts?  Thanks - especially as insurance insecurity keeps me from pursuing with doctors now (though I was told to follow up on the 3mm thing back in March).
