I have two bruises - one on each hip area measuring 2 x 3 .. They are both similar in size, color and locaiton. They are bright purpilish now No pain the area. No known hit to the area or fall. Feel fine although I do suffer from RA and my knees have been swollen and pressume. I am a 51 year old female - weighing 175 - a little overweight but exercise regualrly. The bruises just appeared in the last day.
