After CoolsSulpting on 4 areas (now 14 days ago) I've been experiencing cold urticaria.

I know i have winter toes and raynaud... the cold urticaria itch and are very red (every touch on my skin leaves a red mark). my doctor gave me anti histamine medication as i had a lot of elevated histamine levels in my body. when will this condition go away, Or am i allergic to cold? the machine was a chinese replica but same system as the Zeltic also question 2: when can i do the next area's how many weeks in between i have to wait?
