I’m going to guess these work but I’ve used dog chew balls like it to cure MS (multiple sclerosis) foot tingling like symptoms in my feet before while watching TV or sitting infront of computer.
there are more advanced foot roller bar setups that likely could do similar job.
it can possibly be a nerve in the center of the knee thats causing foot tingling too
