I was coming to the end of a seven mile jog last week when I noticed my achilles tendon was feeling a bit tight. I dismissed it and kept going because I had had to run up a flight of stairs in order to cross a railway line. I managed to go about another half mile and suddenly felt the tendon go into a spasm/tear and I stopped immediately. I could barely walk due to the pain and limped the final hundred yards home. After a week I am now able to walk ok, but every time I try to break into a gentle trot, I get pain from the tendon. I have not been to see my GP as I cannot see that he can do anything to help. Any idea how long it will be before I can run again?
