Hi. Thanks for posting your concern at HCM I would keep a possibility of scratching leading on to bruise. As you mentioned that you have extremely itchy inner thighs, that suggests me a possibility of intertrigo/tinea cruris which you may have scrtached vigorously thus leading to bruising. Bruise is self resolving and once the underlying cause(itching) is taken care off. I normally prescribe an Oral Vit C supplement for faster resolution of bruise. I would advice that you use an antifungal preparation for the inner thigh itching. An oral antifungal might be required, either fluconazole or itraconazole under the supervision of a dermatologist. An oral antihistamine e.g cetrizine once daily will help you get relief from the itching. take care regards
