Achilles tendonitis can be painful and is usually down to an overuse injury of the Achilles tendon; the band of tissue that connects the calf muscles at the back of the lower leg to your heel bone.
The tendon becomes irritated, causing pain and swelling usually from a sudden increase of repetitive activity or from putting too much stress on the tendon too quickly, leading to micro-injury of the tendon fibres.
It’s very common in men within the age group of 40-60, this is because the structure of the Achilles tendon weakens with age, which can make it more susceptible to injury.
Treatment would be an hour to assess, diagnose and treat using an IASTM (instrument assisted soft tissue massage) tool or RockBlade to get the fascia gliding again which would prevent further irritation and to promote new blood flow to the area
An alternative treatment would be some PNF (Proprioceptive Neuromuscular Facilitation) stretching to encourage mobility and reduce swelling and then taping to stabilise the tendon and reduce pressure, followed by weekly 30 minute injury sessions to keep on top of this.
If you wanted to treat it yourself our recommendation would be rest and icing regularly.
