I use to own a salon, what I really like is threading.
Sorry about your traumatized legs but you do get use to it and your person doesn't sound too good if she missed spots. I am too sick to shave.
I had never even heard of sugaring. Sorry I am not any help. But I am intrigued to try it in the future. The one time I did waxing, it was pure torture and she missed a bunch of spots. I still had to go home and shave my traumatized legs.
I'd call the doc's office and ask. If there's any doubt, wear shorts. :)
I do it all the time but I am on oral meds. I had a picc line which kept getting infected for something else so I am not sure without Docs ok.
