ozone veins

So I finished my 4th ozone ten pass and it really seems to be working-brain feels better-temp is up-tongue is no longer a greenish-skin seems better and more.
I am having issues with my veins- every since my doc used my to start doing IPT my big veins on my arms are almost shot. I am going to try a long sauna for about and hour before ten pass next week but I am wondering if anybody has done ozone IV through feet or legs?

After 3 months of ivs ..i had to get port ..insurance covered it with pdn dx ...not sure if you can withdrawl without a big saline flush ..the doc that does 10 pass doesnt know about ports ...
