What you failed to mention in your initial post was your past history of HCC of MS. If the foot drop is related to the MS are your MS docs managing the foot drop? Do you have a posterior support for your shoe? Considering that you’re indicating your foot drop is related to the MS spinal surgery does not always correct this. I’m guessing you’ve been told this and you’re seeking verification of the facts? We are all volunteer patients, so to speak, where we can share our life experiences with others. We cannot offer you any professional advice but many of us are retired healthcare professionals who can help. Good luck!
