Severely sprained ankle 3years ago. gets a lot worse(pain,stiffness)in summer when hot.what could it be and how could i treat it? thank you very much!

Kankle.: I am not so sure that the pain and stiffness is due to the actual seasonal differences as more due to the increased activity levels associated with warmer weather. Having said that, there could be some residual internal ankle derangement from the ankle trauma. This could involve bone, cartilage or soft issue elements. It might be time to have your ankle re-evaluated for treatment possibilities.

Muscle contractures: Your problem is likely muscle contractures or 'trigger points' from the original injury. Torn muscle forms scar tissue within the muscle body; this is non flexible unlike the rest of the muscle fibers. It also pull on the adjacent muscle fibers causing pain and stiffness. Try ice and any of the OTC NSAID/Lidocaine creams/ointments. If that doesn't work, you'll need to see a Pain Mgmt doctor.

Sprained: If it's still painful after 3 years it would Be worthwhile to get a mri to evaluate the ligaments and to see if there is any cartilage damage
