Old hairline fractured foot has throbbing pain and popping after climbing up ban!

Old hairline fractured foot has throbbing pain and popping after climbing up bank, please help!?

I had a multiple hairline fracture of my 5th metatarsal on my left foot over 2 and a half years ago. A podiatrist said that the damage wasn't bad and they didn't need to rebreak it. But I have had trouble with my foot ever since. My foot throbs continuously and just the other day I was climbing up on a bank and my foot really started to hurt. The throbbing became painful and my foot began cracking and popping. I can't flex my foot and can walk on it, but can't put much pressure on it. My foot almost feels like it needs to be put back in place- almost like when you crack your back or a joint to make it feel better? Once the foot "cracks back in place" it relieves the pain a little bit.

I am really at a loss here. I always felt that my foot never healed properly. The pain and throbbing is on the side of my foot close to my ankle. The throbbing can actually be felt like a pulse and with rest it isn't getting better.
What could possibly be the problem? Did I reinjure my foot?

It would be good to see a doctor again to make sure there is not another fracture (x-rays dont show stress fractures, bone scan will). I think there is a good chance that you have a stiff foot that needs to be worked on to gain the mobility back in your foot and ankle. I would recommend you go see a physical therapist to work on the mobility and strength of your foot/ankle that you lost with the previous injury.
