Do you have diabetes? Neuropathy can cause sharp, stabbing pains in legs and feet. I don’t know about itching though. Maybe you have 2separate problems—pains and itching. If itching is feet only, are you going barefoot? New shoes? Different lotions or ointments? Dog licking your feet? Athletes foot? Can you arrange to see a doc soon? they can run tests like biopsies and skin scraping to help diagnose this. I have a full body itch. I’m using an itch relief spray until I can get to a dermatologist
