Be honest with you I must have had 50-60 of them in my knees in the past 5 years to 7 years now. I never had any of them ever make me sick but I had a few of them botched up expecially when they try to do it right in the front of the knee I do not allow that to ever happen anymore they do it on the sides or they don't do it. And sometimes Bill Head something in there whether it's a nerve or or maybe it just run into a bone and it hurts like the Dickens but nothing that severe. Now if I didn't sleep at all and I didn't eat and they did that I could possibly feel lightheaded and nausea easily. But to date I never got sick from it,yet!. I hope that was helpful.

I've had several sets of cortisone injections in neck and down entire back. Only worked for about 2 weeks. Felt a bit ill and sore and migraines for a couple of days then ok.
Same w nerve blocks entire spine. Again ill a couple days. Quit working after 10 days. Hope that helps some!
God bless

Nope no shots here i just take ibuprofen when needed

I'm going to get my second one in my neck. I'm getting the nerves in my neck burnt off but because of insurance I have to do 2 rounds of shots. Yes I hurt and it made me feel sick and sore for 2 or so days then a million bucks for around 25 days. Now I feel horrible and going for another one to get some relief

Definitely
