Hi,Welcome to HCM.
If the pain has not relieved after 4 weeks after the ankle
sprain,It could be
bony
injury of the ankle joint.Any nerve/tendon overlapping with entrapment in the anterior ankle needs to be ruled out.
Hence I would suggest you to get
Second Opinion from Orthopedic Surgeon,who would direct for its management after needful physical and radiological check up.
-Treatment-
Rest Elevation
Post-Below Knee slab if need x for 3 weeks after Xray ankle.
Tab Anti-inflammatory under guidance from your doctor.
Hot fomentation/compresses to reduce edema complicating the issues.
Orthopedic consultation and needful further treatment as directed from him.
Hope this would help you to plan treatment with your doctor.
Will appreciate your review write up and hitting thanks,to help needy patient visitors like you at HCM.
Welcome for any further query in this regard.
Good day!!
