What can cause unexplained pain in my ankle and achilles' tendon?

Many things. The pain you are experiencing may or may not be connected. Ankle pain can result from arthritis, infections, sprain/strains. Achilles tendon pain may result from tendonitis, tears in the tendon, bone spurs amongst other things. Evaluation by a podiatrist or foot/ankle orthopedic surgeon would be beneficial.
