Hello. I have really bad foot pain that started maybe 1 month ago. Nothing changed in my routine: wake up, work, etc. I do have to stand during my train commute, which has just made my pain worse. It was more tolerable before but has become increasingly unbearable, so much so that even when I'm not on my feet, they hurt. They also burn frequently. The pain is on the bottom towards the side and middle, like if you go moving from the middle towards the side where your pinky toe is. But the whole foot hurts. The other foot has similar symptoms but not as bad as my left foot. I have sore knees also which I feel when I go up/down stairs, or get up after sitting for awhile. I have some back problems too, including sciatica. I am also overweight. Any ideas? What can I do? Thank you for your help
