When can I get back to running with Achilles tendon problems?

When . Pain stops.

Depends on severity. Many runners, especially those that are advanced, run with mild achilles tendonitis. More severe tendonitis or partial tears often need a prolonged period of rest (1-6 mos.) from running and aggravating activities. Most benefit from a customized footwear evaluation, physical therapy, and some require bracing or immobilization. A sports medicine physician can help guide you on a return to running.

Couple of things. You need to heel the achilles problem first and work wtih a physical therapist to get running again.
