It can be that your heel pain will dissipate without treatment, provided that you rest your heel and follow some simple stretching exercises, together with wearing supportive shoes, like running shoes for example, to cushion your feet.
Should the pain continue to trouble you, the application of an ice pack may soothe the symptoms. Anti-inflammatory painkillers may help, and a course of physiotherapy may be recommended too.
Some heel pain sufferers have noticed that wearing splints overnight can reduce the pain. Complete recovery from plantar fasciitis typically takes between 12-18 months, but if your symptoms persist, your consultant may propose surgery to release your Achilles tendon.
