Hi,
Water on the knee is a generic term used to describe knee swelling which occurs when excess fluid accumulates in or around the knee joint. There are many common causes for the swelling, including arthritis, injury to the ligaments or meniscus, or when fluid collects in the bursa. This condition is known as prepatellar bursitis.
The type of fluid that accumulates around the knee depends on the underlying disease, condition or type of traumatic injury that caused the excess fluid. The swelling can, in most cases, be easily cured.
Avoiding weight bearing activities as much as possible when the knee is painful and swollen is essential.
Cold therapy can help control pain and swelling. Application of ice to the knee for 15 to 20 minutes every two to four hours is helpful. When icing the knee, it is important to raise the knee higher than the level of the heart, using pillows for comfort.
Acetaminophen (Tylenol, others) is often effective at relieving pain. NSAIDs (Advil, Motrin, others) are effective for relieving pain and inflammation.

Ummm, I think its a hair bump gone wrong..
I have never shaved above my knee before but just recently i did, a week or so later this little blister came up so I mashed it , 2 days later it increased in size little by little it has grown now it looks infected with heat generating from the area , since I've applied the hot (2X'S DAILY)towel it has help bring it up.... I dunno if I need to keep applying and it will eventually bring the hard knot up and out or maybe I should see a doctor to remove it surgically?
Thank you for your time and response...
