Yes! The most common cause of heel pain is called “Plantar Fasciitis” - it’s a funny name really, but all it means is that you have an inflamed soft tissue/fascia at the bottom of your foot.
If you’re getting pain at the bottom of your heel that’s worst first thing in the morning and on standing after rest, a lot of the things you read (and people you talk to) will tell you that you’re likely to have plantar fasciitis. But there’s another muscle that has the same insertion in the heel and spans the arch to your big toe - it’s called your abductor hallucis muscle - and it could be true cause of your heel pain and the reason you’re not getting better as fast as you’d expected.
Athlete’s foot (clinically known as tinea pedis) is an unpleasant fungal infection of the feet. Areas between the toes often get red, itchy, scaly or cracked. Other areas like the heels or balls of the feet can be dry and itchy. Blisters and bubbles can appear and the feet can feel tender.
