- While I think I understand how a differential block works, I would
- appreciate some knowledgeable (and charitable) soul to verify or
- inform me further.
-
- I will be receiving a differential block very soon, and from what
- I recall of the anesthesiologists explanation, it goes like this...
-
- A needle is stuck into the spine, somewhat higher than a normal
- lumbar block, and an anesthetic is injected, numbing everything
- from the chest, down to the toes.
-
- As the anesthetic slowly "wears off", I am asked if I can feel a
- pin-prick at various points along the way.
-
- If at some point where I can feel the pin-prick, I can also feel
- my chronic pain, once again, then the pain is deemed to be "somatic".
-
- If, however, I feel the chronic pain, regardless of level of returning
- sensation, it is sympathetically mediated.
-
- I have RSD, and this is a test to determine if the pain is any longer
- sympathetically mediated, or is simply somatic.
-
- The gist of all of this is that if it's somatic, than one of two things
- will be done to eliminate the pain.
-
- One is "denervation", and the other is amputation. Because of additional
- significant and irreversible circumstances, I will of course choose
- amputation. It's the only way I'll ever walk again, anyway.
-
- But, what I do not understand is this...
-
- It seems to me that I may be misinterpreting part of what I was told about
- the block.
-
- I would think that as soon as the block is administered, and _if_ I still
- feel my pain, then there would be no need to wait for it to "wear off".
-
- I would think that a diagnosis of sympathetically mediated pain could
- immediately be surmised.
-
- Am I missing something here?
-
- Thanks,
-
