Hi again yes i had a stroke in the lower part of the spine 10 years ago which left me unable to walk for a couple of months. I had very little feeling below the waist and reversed sensation in my legs . so my right leg whis is my good leg so to speak i dont feel hot or cold water in the bath but the slightes touch against it even a drop of water on it feels painful but my left leg which is th one i have the knee problem with the bath water always feels to hot even when its not and i am prone to tripping up as my toe often drags I do have more feeling below the waist now but its not back to normal and i dont suppose it will get any better now. Hope this information is what you want Jess
