I don't think I'd ever try anything as extreme as that, but inducing mild inflammation is used in various less potentially crippling situations as well. One example is microneedling of the skin. Inducing damage to the skin through microneedling has been shown [0] to induce a healing response that can promote collagen production. This (sometimes in combination with platelet rich plasma during treatment) is often used for things like scar treatment, skin conditioning, sun spot reduction, and fine line treatment.
