Sclerotherapy Problems with Arms and Hands: I now have tingling and dry lined pruned skin on my hands and fingers.

I had sclerotherapy in both arms and hands 6 months ago and looking for help. Could the Dr have removed important veins in my arms that can cause this issue? (cephalic and antebranchial) Or is the blood re-routed without issue? I am really worried and cant seem to get moisture back in my hands no matter what I do. He told me it was safe to remove these veins. Thank you all.
