Well speaking from current experience, I must say having a doctor that understand would have been helpful for me. I was experimenting on myself with the canned air, now I knew the can got very cold when in use. Then I tried turning the can upside down. I loved the feel of it, so ventured to try more sensitive parts, working my way down to my mound, it felt very delicious, and I wanted more. But not paying as close attention to were I was aiming I kept hitting the same spot three times. The next day I woke up with a blister that hurt awful, but not only was it a large blister, but it was a second degree burn. It was about the size jam lid 3'' . Now had I had a doctor in advance who understood my new lifestyle I could have called to see what could be done. Although there isn't a lot you can do about burns. So for the last two weeks I have suffered immensely. It is finally down to the size of a nickel, but now that it has been brought to my attention, I will be considering how I can communicate better with my doctor or at the very least looking for one that would not be judgmental about injuries. As Baddog pointed out find one now before the need arises.
