hi I m a 16 year old girl I ve been battling a cold for the past 4 days with dry cough, little sore throat and hoarse voice. I recently noticed two circular bruises on my left thigh near my knee. They re dark purple and the size of a dime. I don t remember any possible way I could ve gotten them. One of them hurts like a bruise but one of them doesn t hurt at all. I m just a little worried because I have been reading so many things on random bruises and it s scaring me. should I consult a doctor right away? Or wait? And if I do wait when should I go see one for sure? Thanks
