There is no consensus in the medical community regarding treatment of Achilles tendinopathy. Common treatment options include; eccentric exercise, glyceryl trinitrate patches, micro-current and microwave electrotherapy, non‐steroidal anti‐inflammatory drugs (NSAIDs), corticosteroids, or orthotic treatments such as heel lifts, and specialized shoes to correct misalignment.
Studies have found NSAIDs to have little effect on chronic Achilles tendinopathy, which makes sense because inflammation is not a key factor in pathogenesis.⁴ Corticosteroid injections have been shown to relieve pain on a short term basis, but the effects don’t last. Compared to physiotherapy, pain and functionality outcomes with corticosteroid injections are worse at intermediate and long term follow ups. Adverse effects are reported in over 80% of studies involving corticosteroids and tendinopathy. Corticosteroid injections are also associated with Achilles tendon atrophy, according to a 2011 study.⁵
