Wrist sprain. To take other than this?

Its been a month my left wrist joint ( I guess radiocarpal joint ) has been under pain . One month ago pressure had been created at that joint due to a minor accident where i held my scooty with 1 hand to control the fall due to this my left wrist was twisted a bit .I was in extreme pain for 2 days and there was no swelling  .Primarily i tried ancient immobilizilation technique where the area under pain is massaged and tied properly. But pain hasn't come down .so i went to hospital i am attaching my xray with this .doctor explained there might be a sprain or slight ligament tear and hair line fracture. Its been a month still i cant twist my wrist .when i do there is pain in the joint. I am attaching a google based picture plotted area is under the pain when i twist my wrist. Right now i am under prescribed medication and using wrist brace for support. Kindly suggest me what to do now..How long will it take to completely cure ? What measures do i have to take other than this ?
