Is there any pain over the swelling? Can you move your ankle freely without pain?
When you press on the swelling, do you leave a pit or mark on the swelling?
Has the swelling increased within the last 5 weeks? Or decreased?
Does the swelling decrease when you keep your foot raised ?
Do you have any heart or kidney problems, or a high blood pressure?
What medicines, if any, are you on?
Lets take this one by one:
- If the swelling started with pain which has decreased over time, then it was due to an injury, probably to the soft tissues since it started with wearing a tight shoe.
- If the swelling decreases, even slightly, when the foot is elevated, then at least part of the swelling is due to fluid. Only fluid will flow back to decrease the swelling.
- Feet getting cold frequently and frequent cramps indicates a problem with the blood circulation.
What is possible in your case, is that the soft tissue got inflamed with collection of fluid. What you had was probaby cellulitis - a diffuse inflammation of the soft tissues. This is more serious than a simple infection.
Cellulitis can cause damage to the lymphatic circulation of the affected area and cause chronic swelling .
A repeat MRI will help to check if you do have a diffuse swelling of teh soft tissue. the standard treatment is with compression bandaging.
I hope this helps.
