Hi @Lisa_E66
If you are having ongoing problems (I had them too, and I won;t tell you how long it went on for) ask your surgeon to write a referral to your local radiology dept and get it done under ultrasound. Ask him to OK one of his minions to fire off another referral (or another dozen) as you need them. It's bad enough without having someone inexperienced jabbing away at you --which only increases the risk of infection . I'd use that as the rationale to get it done by a professional.
Never feel shy about asking if someone has the appropriate experience/training to perform a procedure. And refuse to let them practice on you if you don't believe they are competent.
