Is this a heel bruise?

[Elsewheree]

About a week and a half ago I landed hard on my heel and felt pain immediately. I iced it and two days later it felt a lot better so I walked on it and worked. After a few days it began to hurt a lot again only when I walked and the pain was mainly in the heel. There wasn't any swelling or discoloration so I am pretty sure it isn't fractured or broken but the pain is so intense I can barely walk. Should I go to the doctor or do you think this is just a heel bruise and I should give it time?
