The following information was reported: LOCALISED INFECTION (medically significant) with onset Jan2022, outcome "unknown", described as "foot infection"; OSTEOMYELITIS (medically significant), outcome "unknown", described as "osteomyelitis". Therapeutic measures were taken as a result of localised infection and osteomyelitis: the patient was prescribed clindamycin for foot infection. Foot Infection: reporter's parents used to have help that would come to their house after her mother had West Nile but they no longer have that help so the caller has to rely on report from her father. She calls multiple times a day and he didn't say anything about her mother's foot. Her mother in general has horrible twisted feet, they have bunions and are torched to the side, they look horrible. She has areas that protrude and any shoes that she wears no matter how soft and stretchy they are cause rubbing. She believes it is her mother's left foot and on the small toe over that toe joint. It began a concern when the caller first heard about it which she thinks was around the week of 17Jan2022 and then her mom saw the doctor on 20Jan2022. The caller's dad didn't tell her about her mother's foot until either 17Jan2022 or 18Jan2022 and then the caller took her to the doctor on 20Jan2022. The doctor started the clindamycin because she concerned about it being over the joint and she was worried that they could be looking at osteomyelitis at some point. It looks much better according to her dad.
