During a Sesmoidectomy on RF in 2008, I was informed by the DR (during post follow-up)
"My assistant had to spread the foot incision wider in order for me to get in and it required compressing the Deep Peroneal Nerve".(DPN).
After that surgery I experienced Immediate cold burning throbbing pain on top of foot at the web space of 1st\2nd toes. It was horrible and constant. I was then put on Vicodin for awhile, then I found a D.O. who treated pain mgmt with "RFA" RadioFrequency Ablation). A electronic needle that burns the nerve just enough to disrupt the pain signal to the brain. It worked, for abour 3 months then repeated with longer relief gains. The problem was in trying to find such a small narrow nerve with Ulrasound and the nedle, the pricking the web space with a needle trying to find the DPN resulted in the DPN in the web space becoming injured by the needle over time (Found that out later by Neuro. After a few years of that....I sought a Neurosurgeon for opinion and after ordering a a nerve conduction study (NCS), it revealed the DPN in the web space was screaming in pain.
The Neuro did some other tests (Foot Nerve Block) to see if that indeed was the DPN causing the pain. He then concluded that "The DPN in the foot was likely diseased and recommended a Neurectomy and cut out a 1inch piece of the DPN between 1st\2nd web space. After THAT painful recovery (1.5 years) the pain went AWAY..
Page foward 14 years to now and AFTER the TKR procedure my foot is SCREAMING in pain and cold burning..
I believe its due to either

1 - The tourniquet on the upper thigh, or
2 - Deep Vein Thrombosis (DVT) I developed (Or was sent home from the hospital WITH) 1 day after I was discharged from TKR and the nerve block wearing off. I was made aware of the DVT at 7 days post when I couldnt move the leg due to intense pain or get out of bed. THe home Therapist who came to start 1st day of post surgery home therapy saw how swollen and reddish\purple my lower leg was and called the Dr office and they said to "Get him hear now". Had to go by ambulancedue to not being able to move my leg or bend it(7 days post TKR and never made it out of bed). They did Ultrasound and said 5 large clots found) sent me home with blood thinners (And the excuiating now lower leg pain of DVT pressure throbbing pain like you can not imagine). So at that point I was dealing with having to recover from a TKR and NOT being able to begin threapy or get out of bed, I'm also dealing with DFT and intense lower leg pressure pain. When the DVT pain started to subside (2-3 weeks later) I began feeling the DPN pain in the foot web space which I have at this moment as I write this (5 MONTHS POST TKR)
