i was treated for hpv a few years ago which required a few visits requireing freezing to the affected areas. the first visits the dr made it clear that each area would be treated with three blasts each with a pause in between. the last time i went i was treated by a nurse who proceeded to continually spray a large area for some time causing alot of pain and swelling. the area became scarred as an area of white pigment and is very noticeable. i was told it would heal itself back to natural skin color but never has. im wondering if i have a malpractice case as this has caused alot of personal issues and i would like to pursue some way to correct the skin discoloration which i assume would be spendy.
