I have a red spot on the top of my third toe, it is slightly painful since I have picked it and I'm worried that its something serious, should I be?

Since your concerned. In order for you not to worry and stress out it would be wise to show a doctor. It may be something as "silly" as an abrasion from rubbing on your shoe, or a bursitis developing. But, sometimes it can be something more serious. The only way to know would be to how someone it with experience to make the diagnosis. Stressing out though doesnt help.....
