Hello! I, unfortunately, have Lichens Schlerosis. They did a "punch biopsy" on me right in the office & it's like a quick pinch. Not too bad, and aches like a small bruise for a day or two. My dermatologist is treating me with steroid creams {3 different ones}, but it's hanging in. UGH! It has become much milder over a long period of time...
They take what is called a skin punch, in other words, about an inch's worth of skin. This will be a deep sample of your skin, and it takes about 3 months to heal. They cannot use stitches because you need your body to naturally regenerate such a deep puncture. It will puss and bleed occasionally. Also, it will itch if you are testing for lichen sclerosis and think you have it. You can walk easily, it is not a big deal, however, it is advisable to apply A&D, bacitracin, neosporin.. anything that protects it from infection. Any urine that passes over the biopsy sample will BURN! It is such a horrible feeling, the acidity in your urine will cause your sample to bleed, further continuing the cycle of not being able to heal.. so apply something on it! Vaseline based!
