Varicose Veins...gotta 'em too?

 I have several collapsed varicose veins, especially behind my knees, and I'm wondering if you've got them too and if you have heard about any treatment for them.

I'm finally writing about this because I think mine are getting worse, are causing leg twitches at night, lower leg numbness or a dull ache during the day and sometimes tingling in my feet.  I'm guess all that is due to circulation and blood flow to my calves and feet not happening because of these veins.  I did just get a referral from my PCP to see a specialist, but the earliest appointment I could get is August 6th!  eeek.  

In the meantime, got any advice?  I stretch my legs several times a day and elevate at night, which helps; not sure what else I can do.  Have you had any procedures done or any that you know of that work that I can research between now and the August 6th appointment?

Much appreciated,
Kimberlee
