What is the blue bruise line at the middle of my upper leg upto knee?
Patient: i have a blue bruise line starting at the middle of my upper leg (quad) and ends just before my knee. The line is straight and about a quarter of an inch thick. i did not bang into anything etc but i did just go for a run. It hurts a little bit at the top when i press on it. Doctor: Hello,  It may be a linear rash due to the impact due to the stitching point of your dress. It may be cutaneous larva migraine or urticaria.  But until the examination is done it is difficult to say what it is. Apply moisturizing cream.   Please consult your physician he will examine and treat you accordingly.  Hope I have answered your query. Let me know if I can assist you further.   Take care   Regards, Dr. Penchila Prasad Kandikattu, Internal Medicine Specialist
