I have a very bad pain in my heel it's been 2 months that started, pain is getting worse, i dint twisted or hurt it in any way, what can be the cause?

Plantar Fasciits: Swelling of the plantar fascia on the bottom of the heel causes a lot of pain. Since heel is the first part of the foot that hits the floor when we walk, it continues to stay swollen. Must go see a podiatrist and you can apply ice at this time until you get in and see a podiatrist. They will be able to help you more, you may possibly need a cortisone injection if the case is severe and acute.

Plantar fascitiis: Can be as painful as you describe with no recollection of history of trauma.

Plantar Fasciitis: A tight band of connective tissue on the bottom of your foot is pulling on the bone causing inflammation.

Plantar Fasciatis: Is the most likely cause. Go to a podiatrist I am sure they can help you.
