Within hours she was on her feet and free from pain.
Three months on, Mrs Wilks's health is going from strength to strength and she can do the school trip to Beechwood primary school with Reece unaided.
Mrs Wilks, 45, said: "I am feeling great. Everything about my health seems to have improved so much. It is the small things that mean so much to me - the little victories..
"My legs aren't perfect but I can stand for longer and hang out my own washing on the line. I am not in pain, I feel stronger and I am not sleeping all the time.
"I can play games with the children. I have more patience and energy. Sometimes I catch myself walking upstairs and can't believe the treatment has worked so well.
"The kids are made up with me. I feel normal again. I am back at work and everyone says how well I look because all the pain in my face has gone."
One of the highlights of the summer was a family holiday in Cornwall where Mrs Wilks was able to build sandcastles with her sons Reece and Daniel, 12, sit on the beach and go out for the evening with husband Paul.
