I was wondering about a skin condition called atopic dermatitis, because I feel that I have it. My knee is secreting this clear fluid that is crusting up. Currently, the entire knee cap is covered and there is some of this on the back of my knee as well, in the fold. This is happening on my right leg. I am itching on most of my limbs, but they are not creating this fluid. Research on it shows that it will just disappear over time, but unfortunately come back. This is the second time that this has happened, the first was last year and it was all over the elbow of my right arm. I went to the health center and the dermatologists and they could not identify it. Money is a problem for me and the tests last time charged me greatly. I was wondering if I should see if it goes away after a while like the one on my arm did last year or something else?
Unfortunately, what you are describing is not typical of atopic dermatitis, which is usually quite dry and doesn't ooze fluid unless it is secondarily infected with bacteria (potentially quite serious). If you have had it looked at in the past and there was no diagnosis despite testing, then it is not the most common things like atopic dermatitis (also known as eczema) or psoriasis. There is no cost to coming back to the health center to have it reexamined as testing does not have to be repeated, but it may be more obvious to us this time.
