My son has RSD and goes to pain management. Much medication and I worry. He had to go to emergency room for his toe was bleeding and would not stop. He was given a tetnus shot. Sorry if I misspelled .He lost his vision and the eye doctor said it was a stroke from the shot. . Is this true. I am sorry this took to type so long but I have blepharospasm of the eye lids and Parkinson disease. How long will his eye sight return. He could see straight ahead but not on the sides. He cannot drive a car. I have to hold my left eye lid up to be able to type with one finger. Thank you Doctor and God bless you.
