Heel pain mostly relates to Achilles tendon injury and overload. Rarely does the tendon tear. Ultrasound can accurately confirm the degree of injury and local inflammation changes. Most tendon flare-ups recover with physiotherapy but some require a very specific injection called high volume distension that removes abnormal vessels formed within the tendon. Patches (Minitran nitrate oxide donor) applied over the tendon can in some circumstances help the full recovery.
