Treatment for Achilles Tendon Pain
Nonoperative or nonsurgical treatments should always be considered first!
“Traditional” treatments such as rest, therapy modalities, orthotics, and NSAIDs have all failed to demonstrate benefit for Achilles tendinopathy patients. 
Passive modalities including ultrasound, electrical stimulation, and low-level laser also lack support. 
The current standard of care for Achilles tendinopathy includes a combination of rest, eccentric rehabilitation, and correction of mechanical faults.
Studies have demonstrated excellent results in up to 85% of patients undergoing appropriate conservative care. 
Initially, you may need to limit or stop activities that are causing “damaging” type pain such as sharp, shooting, burning or tearing pain. Significant strains may also require the use of supports including crutches or a boot. Runners may need to switch to swimming, cycling, or other activities that limit stress to the Achilles tendon and allow it to heal. Patients should avoid shoes with an excessively rigid heel tab to reduce irritation.
Soft tissue manipulation, stretching, and myofascial release techniques are necessary to promote flexibility of the calf muscles as well.
Stretching of the calf muscles should be performed with the knee straight to address the gastrocnemius and with the knee bent to lengthen the soleus.
