For a couple of months, I've had deep, dark red streaks that look somewhat like miniature tire tracks on the back/ inside of my thighs. Really starting to worry, though they cause no discomfort. Please help?
Hi Travaverse. There is an infection called Bartonella that you can get from a tick bite. It can cause marks that resemble stretch marks or scratches. I suggesgt looking at Bartonella rashes to see if yours resemble it.
It is always a good idea to get photos of any marks or rashes. Place something near them, like a coin or ruler, before photographing to give them size definition. Then you have documentation of them.
