<s>[INST] What is the matter with my right foot and ankle? My entire foot is swollen and aching- sometimes it feels like it is burning . It hurts to touch parts of my right foot and ankle . Prior to this I was experiencing almost no feeling in either foot. i have had both x-rays and a bone scan done - no diagnosis available. Any ideas ?? [/INST] Hello, I have studied your case and I think that it might be nerve compression in the foot. I would recommend you to get MRI of the spine to see if there is nerve compression is present in the spine due to disc herniation.  I would recommend you following.1. Tablet Pregabalin M one daily.2. Avoid forward bending and weight lifting.3. Elastocrape bandage is also good for swelling. I hope this answer will be helpful for you. Let me know if there is any other followup questions. Thanks </s>
