If the doctor is good and knows what he is doing. you should not many problems. First eppies are to be done in a set of 3. Normally over 3 to 6 weeks. If it works you will have releife. They need to be done back to back. Also there are many meds that can be used to chill you out. Ofter you won't remember a thing. Also the doctor should use a scopr/x-ray unit to see wjere he is with the injections. If done properly is a set a 3 more likely than not, you will feel great for months. Remember you need 3 eppies back to back to get the most out of it.
