lower leg tingle/weakness

Hi, my problem is when i,ve ran for 15 min,s my right toe starts catching the ground and i get a feeling of not being in control of it.
When i cycle its the same but take,s 20 to 30 mins to come on but then its my knee that numbs up and my foot gets the same feeling init.
I did damage my ACL ( annular tear) the same on my meniscus a couple of years ago i had no surgery on it.
I read the pereneal nerve runs through the knee & down the leg could this be my problem.

Don't mean to cause any panic but if a non weight bearing and a weightbearing activity cause similar symptoms of altered sensation, you may be looking at a vascular problem i.e. blood circulation compromise. I would suggest you to see your doctor on the side of caution.
