Blue Leg Bruises Blue Spot On My Moms Leg And It Isnt A Bruise?

Blue spot on my moms leg and it isnt a bruise? - blue leg bruises

My mother has a bruise in my legs growing every day, I received over 3 days, I woke up and said he noticed that his leg was suffering, it's like a bruise, but he did not because my mother was asleep, I could also have sciatica
She is eating very healthy organic vegetables, but always seems in a bad condition, can someone tell me what is it?
