I was kept awake last night for the whole night apart from 1 hour at the start and between 5 and 6 in the morning. The pain is in 1 toe and it is like an electric shock lasting less thn a second , but it returns often, every 4 or 5 minutes. I take it it is a nerve pain. I thought it would go away with paracetamol but no. walking round did not work. It has carried on today. Sometimes it's every couple of seconds. HELP what can I do.
