i am a runner and recently i have had pain in my big toe which aches & feels uncomfortable to stretch. There is also a red mark on the outside of my toe joint. i have had bloody test for arthritis etc with no concerns. Any thoughts?thanks
Painful big toe in a runner.....negative blood tests....my first thought is a stress fracture.
See if you can get a MRI scan either privately or on the NHS and Internet meantime, cease running and take Ibuprofen 400mgms three times a day.
