Im no expert, but it sounds like you might be sitting too low on your throne. Are your legs at a 90 degree angle while playing? Too low and youre hurting your knees.
Does sound a bit like a setup issue also could be fatigue, tension in your legs. Try stretching before you play to see if that helps as well. how long have you been playing double bass and what is an "extended period of time"?
What kind of throne do you use? I would get some serious right leg fatigue (i don't play double bass) before i switched to my roc-n-soc throne. I used to use a regular round seat made by taye.
I do use a regular round seat by DW, so this could be the problem. I'll have to look into a Roc-n-Soc or something with a back rest.
