[|Human|] My uncle was on a road trip drove 8 hours or more had partial knee sx now has big black bruise behind knee. My first thought was broken blood vessel or tear,sprang he went to er did vitals and sent him out. His vitals were stable i put ice on it. Gave him tylenol and ibuprofen he says pain is distal to bruise. Should i tell him to take baby aspirin or will it make it worst. What do u think
[|AI|]  Hello possibility might be a leaking Bakers Cyst. This is a small cyst behind the knee that can sometimes leak fluid. The fluid can track down the leg and cause discomfort in the calf area. This is a benign condition and doesn't need any X-rays or scans you can give him Tylenol or ibuprofen. Have him elevate the leg a few times a day if possible. I'm sure it will get better in a few days. If he develops more pain or swelling then please take him to the ER for assessment. Best wishes. A Chat Doctor.
