After walking in high heels, the muscles in the back of the foot tend to become fatigued and tense, which in turn causes muscle clonus, soft tissue damage, etc. This can lead to pain in the back of the foot.
If the pain is temporary and caused by unreasonable, prolonged wearing of high heels, it can usually be effectively relieved by changing to suitable, comfortable shoes. If the pain is prolonged, the possibility of plantar fasciitis should be considered and is currently treated mainly with physiotherapy, but can also be combined with medication.
Plantar fasciitis is a chronic strain caused by prolonged activity and often results in chronic pain on the bottom of the foot or around the toes.
