I woke up on Wednesday with severe pain in my left big toe. I went to work and worked all day and the pain got worse. My foot has swollen, and is very painful. It is now Friday, and the same thing. I had it happen a few years ago in my knee and went to the doctor. They did no tests but told me it sounded like tendonitis. what do you think? I am also a weightlifter and did heavy legs the night before.
