I am sorry you are not cleared to ride. Keep up with the PT and ride your trainer when you can and you will be back up and riding soon. I know it is not as soon as you would like. You have been dealt a lot to handle in a short time frame. Humor them with the dye. I know it stinks, but it is a very good test. Hang in there. I know it is very cliche, but take things one day at a time. (((((Hugs)))))
