Ankle and Foot issues.

Hey, I've an ongoing ankle and foot problem that is preventing me from football.

Long story short, basically I kicked a fella on the leg two years ago now playing a match and broke my 2nd metatarsal, and also ripped the tendon sheet in the middle of my foot open. The metatarsal healed, however there is a tiny piece of bone in my foot still floating, secondly my tendon sheet never healed and there is a soft lump in the middle of my foot. This causes me pain when i kick the ball hard. Is there any way to repair the tendon sheet?

Secondly, when i went back playing last year i buried the same foot (right one) in the ground and snapped my deltoid ligaments. This has stopped me playing since last august. As when I go back to run or kick a ball even softly it swells and the area around the piece of bone that sticks out on the inside of the ankle becomes enlarged. All this area can hurt for up to a weak afterwards and is beginning to become highly annoying, as I had planned to run a marathon in October and this is impinging on my training.

Any help or suggestions would be greatly received, and advice would be acted upon.

Thanks.
