Hey! Ok so for several years actually I have had bruising for no reason mostly on my legs. I blew it off because it only came in periods and I didnt think anything was wrong. I just turned twenty and lately the bruses on my legs have been ridiculous! They all come at the same time and sometimes I can have up to like 15 bruises all over my thighs. They look horrible and most of them are big. They all start to go away at the same time and its not long again before my legs are covered again. Its constant now and was reasonably at the obgyn and told them my concern and they took blood work and told me nothing was wrong with that. I think they checked my blood count? Is there anything else this sounds like that they could have not seen by checking my blood? Im a dress kind of girl

Characteristically, the skin eruptions occur during the luteal phase or the late pre-menstrual phase of the cycle. This is when the blood level of the sex-hormone progesterone rises. The skin rash happens as an autoimmune response to the bodies progesterone, hence its name. Within a few days of menstruation when progesterone level falls, there is partial to complete resolution of the rash. It will recur during the next cycle. Some patients have had previous exposure to external progesterone in the form of oral contraceptive pills. This is thought to pre-sensitize patients to react against their own internal progesterone. However, not all patients with APD are exposed to previous hormone therapy. It has been postulated that these patients produce an altered form of progesterone that incites an immunologic response against it. In another theory, progesterone is thought to heighten a patients' hypersensitivity response to another allergen. How does progesterone dermatitis present? A variety of rashes has been described. The most common are urticaria and erythema multiform. Other presentations include
