And describing quite well a problem with your Achilles tenant. It is the worst healing injury in the foot and ankle. It can be very difficult to resolve. You need to to learn how to ice massage with ice from a frozen Dixie cup. and stretch your calf and Achilles tendon. While you are walking you are not putting as much stress and stretch in the tendon. Ibuprofen or Aleve is helpful.
