...i got them? i keep waking up to bruises on my knees and thighs, i have no clue how they happened as of friday i was bruise free and now i have 9 bruise and i haven't done any physical activity that would make bruises on my knees/thighs except horse back riding but i would only get them on the insides of my knees and only 3 of the bruises are on the inside knee the rest are on the outside and in the past two days i woke up with bruises that weren't there after horse riding for a few days and they were on the outer part so any idea what could cause this um like im underweight and the only fruits/veggies i've eaten are the flinston vitamens every morning so any clue what this could be

o yeah and i am a girl if that changes anything and i'm 14 and 5'6''
