I was wondering, I got a shot last week for what they think is torn cartilage. The pain was supposed to go away within 24 hours and the shot was supposed to of kicked in by yesterday if it was going to kick in at all. The pain from the cortisone shot hasn't gone away, the pain I was already having is twice as bad--I can't write with my arm anymore. It's been eight days now and no improvement at all. Do shots take longer to take effect in people with FM/CFS, that anyone knows of? I'm really hoping the effects are just delayed, because the last option is surgery...so I was just curious. Thanks, Danielle.
