I do have PN too in my left foot and ankle. Mine is a dull ache at times, centered on the top of the foot going left. I do have swelling. I also get numb and pins and needles. I am taking B12 on a regular basis. I use a topical Lidocane patch, and a rub in with ketamine in it. When really bad I have other things that I try to avoid. The ache stays all the time. ginnie
