Even the best black belts get gi burns. The neck is the usual place to find them. A good cross choke always seems to leave me a beauty or two. They don’t cause a lot of pain, just discomfort. Especially because they aren’t confined to the neck. Lets just say you never know where you might end up with one after a intense roll. I have posted a story in BJJ Freak Injuries about my instructor getting one under his eye lid. You know how some times a paper cut can hurt worse then a deep cut? That is how gi burns bother me. I had to find a way to speed there healing. Especially the ones where clothing might rub, like the collar of your shirt. I experimented around, with different burns and over the counter creams. I had a ample supply of gi burns and tried a number of remedies for them over time. When all was said and done I found that Hydrocortisone worked the best for me. In most cases, when used the night before, I would wake up to find most of the redness gone and no discomfort when it was brushed or something came in contact with it. It has become my Gi-Burn-Be-Gone. I hope it helps you too.
