Jim, I didn't realize that the after-affects of an injection could last for that long...that certainly explains a lot to me!
I have a guided image hip joint injection scheduled for Wednesday. First time I'm having one right in the joint, so not sure what to expect in terms of pain, etc. but at least I know now that if it lasts for awhile, it's probably just taking it's sweet time, so I don't need to panic and worry.
hugs,
Pam
