It is very important that you get a solid diagnosis here as soon as possible. CRPS (RSD) is one of the most misunderstood conditions in the human body, even by professionals. What type of injection is your husband scheduled to have?

Yes, your husband does have many of the symptoms of CRPS. But we're not doctors here and your husband needs to find one that is familiar with CRPS and is able to distinguish between that, TOS, etc. CRPS can be both underdiagnosed and overdiagnosed.

Point blank, you need to bring it up and ASK the doctor about the possibility of this being CRPS.

And also ask the doctor how much experience they have with it. My diagnosis was delayed as well as I spent months in a camwalker waiting for my foot to get better when instead, my foot exploded with inflammation and pain. Having that toe immobilized solidified my CRPS. Very important to gently keep things moving.

And yes, it can definitely be caused by an operation. Mine was a complication of a fusion surgery on my big toe. I definitely can relate here.....I am not blaming my surgeon, but it would sure have been nice to get a quicker diagnosis so I could have started my treatments earlier. Can't treat something effectively until you KNOW WHAT IT IS!

Good luck to you but dig in and get aggressive. Don't be afraid to seek a second, third, fourth opinion here. Some doctors have virtually zero knowledge base with CRPS, others can be very helpful. Time is of the essence.

This forum is a good place for both information and support. Good luck to you guys!
