Hey, guys. Been struggling with osteoarthritis for 6.5 years. Been getting caudal steroid injections for years, always under twilight sleep. Got a new doctor (old doctor left the practice) and he did an injection today a little higher up, but without anesthesia or any kind of meds. Besides some lidocaine. Is this normal? Is this what I have to expect from here on out?? I was so panicked and scared, and it was quite painful. Can I request sedatives? They already make me have a driver for this, even though I was in and out of the office in less than half an hour. They treated the whole procedure very nonchalantly as I lay there sniffling and hyperventilating a bit. I know I'm a baby, and I can handle the pain level of the shot, but the whole process makes me so anxious. What have your experiences been? Twilight sleep? In office with no meds?

I'm a first year PhD student who was great at stats during my MPH, but now that I'm trying to brush up on the basics nothing is sticking. But when I search Google for Statistics for Dummies or beginner statistics it takes me back to things like mean, median, and mode. I need help from like tests of comparison being the beginning. Like an intro biostats course. What books should I look for? What videos should I watch? How do I google this??

For example, I remember null and alternative hypothesis, but not how to make decisions on what type of test to run based on those. Start me there. I appreciate any advice you can give. I'm floundering.
