want to ride/bulging disks

I would still like to ride. I have 2 bulging disks that are bad enough I do not want to use my back for side to side balance. I have weakness and numbness and lack of control in my legs. I will Have to use a very tall mounting block because I cannot lift my right leg. As bad as that sounds I have found that a short ride helps with the pain. The problem is I can only ride for a short time 15-20 minutes… :mad: Any bracing or other suggestions that might help to extent my enjoyment of my horses? The problem disks are in the lumbar region. I have no insurance at the moment so Dr or chrio suggestions are out. When I do get insurance I am sure it will be a very long wait (6+ months) to get to see anyone that takes a medical card.
