<s>[INST] My toes on my right foot are numb. I can move them but they tingle and I can not really feel them. this happened after some acting dance classes, like two days later. My foot went to sleep but then my toes would not wake up. How bad it is fluxuates- eating seems to effect it sometimes, and walking allot. I also have dark urin in the morning and Ive had cancer twice. Sometimes I think it has finally gone away only to flair up again. I am not a diabetic. I weigh 120 pounds and I eat healthy & I am gulten intollerant. [/INST] Hi, This can be caused by 2 things per say, though there can be innumerable causes for the same.1. Peripheral neuropathy2. Nerve root compression in your lower back.If you are not having diabetes, the chances of neuropathy are less but it can still happen specially with vit B 12 deficiency which your anti cancer drugs can cause. For other condition, you might be having pain in lower back for that matter. Any disc herniation, nerve root edema or compression can cause foot/toe drop. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Rajesh Hingwe, Orthopedic Surgeon </s>
