@julkun I had the terrible burning feet when my SFPN really started about 16 years ago, but then it lessened. I don’t remember how low long before it got a little better…..wish I could tell you. But ever since I continue to have very warm feet and tightness, which feels like swelling in the tops of my feet, above the meditarsal area. (Both feet) I sleep wisest an cover off my feet and have ceiling fan running all night…….anything to keep them cool. I can fall asleep, but after about 6 hours the heat in my feet wake me up. I often take 25 mg of Benadryl at bedtime to help me sleep. I don’t take any pres drugs as they can cause other problems. I’m 82 and wish I could walk and feel my feet normally. I think I’d have more energy. Feels like I’m walking on stones. Wishing the best to you.
