You don't always end up with clots, many go for years with testing, diagnosis & treatment and no clot happens, just something to be aware of- the possibility.

You're pregnant now? How far along?
Possibly the extra fluids and water retention during pregnancy are are part of the cause.
The body tissues loosen & expand during this time so maybe after the baby is born things will go back to normal?

What other symptoms are you having?
pain, tingling in the little finger/ring finger, other?

I did have dizziness but not related to arm position.
