According to the Pain Management Dr., he concluded that indeed, I do have at least stage II RSD. I have these symptoms: coldness in my left foot that is several degrees below the temp. of my right foot. This gets worse when I have PT or over-do it. I also have skin sensitivity to touch or air (feels like a bad itch...you just want whatever is touching it to STOP!), my knee area turns purple and blotchy after PT or doing any kind of "work" with my leg/knee. Note" it's definetely a different color than my other knee, even by a shade when doing nothing.
Also, my toenails on my left grow MUCH faster than the ones on the right since my TKR. All classic signs of RSD in stage II. The Dr. put me on Lyrica, which has helped with the coldness and the sensitivity to anything touching my knee or surrounding area.
The fear that both my current OS Dr. has along with the Pain Management Dr. is that aggravating the knee can put me into an advanced stage II or possibly a III. That's why the current OS Dr. said "therapy that will not aggravate the knee".
From what I am told, some RSD patients go into "remission", which can last for a short period of time with flare ups, or the remission lasts for years, possibly with no flareups at all. However..if you have RSD, you have to always be aware that things that you do can cause a flareup or cause you to come out of remission. That is what I have been told.
I am always in the process of researching RSD, as this seems to be the contributing factor in my current OS to convince me NOT to have a revision. Note: I have not been told that I need one...only that having one would not be in my best interest due to the RSD factor. I'm hoping to find somebody on this support group that got a diagnosis of RSD and/or nerve damage after a TKR.
Also...I signed a waiver before surgery that stated all the possibilities that could happen (negatively) during or after surgery, and nerve damage was one of those "things". With sooo many things to sign before surgery, this is the most important piece of paper that EVERYBODY should read. I, like most peope I'm sure...just skimmed over these items and just signed away, giving permission to the OS to do the surgery.
I will explain the nerve damage that I have: along with the RSD, the nerves that tell the muscles, tendons and ligaments to work (the ones surrounding my knee...especially in the back side of my knee) do not send signals to my brain help bend and straighten. Those nerves have either been permanently damaged, or may repair themselves..in time, so I'm told. Again..."we just don't know".
Oh...I keep forgetting to tell everybody that the tourniquette they put on me during surgery was possibly pumped up too tightly...another post-op nightmare. My upper thigh was in pain for 10 weeks postop...you couldn't even touch the area where the tourn. was or I'd scream. I've been lucky in that regard that that area has "repaired" itself and I am painfree in that area. I will need those op notes (?) to see how much they pumped that thing up to see. I've researched that, too. As you can see, I'm at a "we just don't know" stage, as well as "we need time for the nerves to heal, if they are going to at all", and "you have to be patient" and "I'm rushing things".
That's where I'm at. I hope this clarification has helped all of you that are trying to help me...there is just soooo much detail that I've been given and my head is spinning. I quite literally have had to write things down in order to keep order of events straight!
I'm not the "typical" TKR patient, but I sure wish I was. If I were, I'd be back at work, walking and enjoying my life...just like they said I would be.....in 8-10 weeks! Yeah, right~~~~

....(gotta keep a sense of humor, right???) thanks everybody!
