We never know what to expect with these things.
I have a VM throughout my left elbow and forearm, I have gone through similiar doctor issues and I have found that the best bet is to see a specialist if at all possible.
Once, my diagnosis was final ( I had about 7 or 8 misdiagnosis before getting it right) I found a specialist and saw him.
I've had sclerotherapy done with Dr.Yakes and it has helped a tremendous amount, I also now have a specialist a lot closer.
I would check the find a doctor page, and see if any of them are close to you and get their opinon.
