I injured my knee on July 2, and now there is some fluid on the anterior part of my knee. It aches a little when I am on my feet for long periods of time. Is there any way to treat it w/o going to the dr s office? I have been wrapping it and taking ibruprofen
You can try using hot pack for 10 to 15 minutes and post that apply some pain relieving ointment repeat this two to three times a day.  As well do simple knee exercise like in a long sitting position legal straight press knee down or tighten your knee and front thigh muscles hold for 5 seconds and relax.  If it relieves with this great but of not then you need to visit doctor for proper treatment management. I Hope it was helpful to you.  Take care
