It seems like almost everyone who uses mots-c ends up with injection site reactions at some point, they are that widespread. Those kinds of allergic responses do not resolve on their own, and the best case is that they stay the same rather than worsening. Anaphylaxis is possible, though it appears fairly uncommon relative to the number of people who develop local reactions. In practice the choice comes down to tolerating the discomfort or itching, or stopping; a slightly longer needle so the injection goes a bit deeper into the subcutaneous fat may help, since the skin presumably holds more immune cells than the deeper fat tissue does.
