Could Reddish Purple Bruise On Eye Be Related To Post-concussion Syndrome?

Thank you. I woke up with a reddish purplish bruise on the outside corner of my eye. It is not painful and it looks like someone punched me. The bruise has been turning dark blue and expanding in a lighter shade. I am dealing with post concussion syndrome for seven and a half months now and I have frequent pain around the eye socket and yesterday had tenderness on the temple. I also had tingling and numbness sensation on the same side of the face. I am worried. Could this be related to post concussion syndrome?
