Unexplained bruising

[Jonnie_Dogg]

Hi,

I have a torn anterior cruciate ligament already diagnosed and I am waiting an operation. I had started running again and fell badly, with my knee this time going in a sideways direction. I do have concerns that I may have now also damaged one of my collateral ligaments. However, my immediate concern is that it has been over 2 weeks since I re-injured my knee and today a number of large bruises have appeared on my injured leg. The worst of these are actually on my calf, although it does spread all the way to my injured knee. I was wondering whether I need to get these checked out, or whether it is a normal side-effect of ligament injury? I didn't have any bruising the first time around, only swelling.

Any help would be very gratefully received.

Jonnie

Hi
Welcome to the MedHelp forum!
The bruises could be due to internal bleeding from torn capillaries. The other possible reasons are low platelet count, clotting disorders, fragile spider veins, deep vein thrombus, deficiency of Vitamin B12, folic acid, or Vit K, a liver disease or certain cancers (less likely in your case). It could also be due to pressure urticaria.
It is difficult to comment beyond this at this stage. Since you are waiting for a surgery, it would be wise to get a thorough clinical examination and investigation. Please let me know if there is any thing else and do keep me posted. Take care!

I hope you chose to get your leg checked out for the internal bleeding evidencing itself as bruising that you were having.  If so, what did the doc say?
