<human>: Can you give me the gist of the text in a nutshell?

I don't know what to think really, my partners 10 year old son has been in pain for weeks now and has had blood tests and urine samples tested. There is blood in the urine and he has been waiting for 3 weeks for an ultrasound of his kidneys. This came about after being in agnosing joint pain which was accompanied with a temperature. The blood test results have come back now also and the doctor has said it's pointing to stills disease. Since I've got home I've been searching the internet for information on this and well I'm extremely worried as you can expect and it's hard to take in the information on the internet.
<bot>: My partners 10 year old son looks like he has stills disease after blood tests (awaiting confirmation through MRIs etc) and I want to know what reddit can tell me about this.
