Left ankle feels like it constantly needs to pop. pain with weight bearing on my left ankle. several ankle sprains in the past. what could be wrong?

Small bone chip: You may have a type of fracture associated with ankle sprains. See a podiatrist or orthopedist foe an examination and treatment.

Laxity or defect: A joint feeling like it needs to pop is a nonspecific symptom but after several sprains & continued pain, your ligaments may remain lax (stretched out) and allow for instability of your ankle. Also, we sometimes find cartilage defects after ankle sprains. X-rays, brace and rehab would be first on my list.
