Plantar Fasciitis is a pain (quite literally) in your heels and arches. It starts with almost no warning. You could get it from dancing in a wedding or right after your first 5K run. Sometimes it even starts after simply walking. Once the pain starts, it stays for a long time. Plantar Fasciitis is extremely common in India. I know of people who have had this pain for years. It is like sports injury that refuses to heal.
