I get it, but it doesn't seem to be task specific. My feet used to burn, but I have now been off work for 10 weeks & therefore not on my feet as much. Since then, I have developed tingling in both my hands & feet, sometimes progressing up my forearms & calves. It comes & goes several times throughout the day. Now & again, the tingling morphs into burning in my feet, but it doesn't usually last very long. Before, the burning was chronic, often waking me up at night. My 22 year old daughter is going to a pain clinic in a couple of weeks & will likely come away with a diagnosis of fibromyalgia. She gets tingling in her legs too, has since she can remember.
