I've been rebounding at home for years. I don't need to lose weight but do it most days for my mental health. I also suspect I have ADHD and cardio exercise seems to help with the constant chatter.
Recently I've noticed a sore 'twinge' in the back of one knee. It's not bad, but noticeable. I don't take much interest in exercise beyond the immediate benefits so don't know, but if I continue rebounding am I setting myself up to tear a ligament/tendon/whatever?
The pain feels like a line of about 2 inches long which is why I think I might tear something. I'd absolutely hate to keep going because it's not that bad and then injure myself to the point I can't exercise at all 
I took a week off exercise recently and the pain was still there, but dropped from say 4/10 to 2/10. Went back to it and it's back to a 4.
Just looking for some advice from someone who knows a bit more than me to give me a heads up if I'm about to fuck my knee up I guess!
