腳傷一問...

腳踝扭傷(ankle sprain)有80%是向內扭傷(inversion sprain),其中有高至三成機會扭傷外側靭帶(lateral collateral ligament),大部份不需做手術,可靠物理治療(physiotherapy)和穿上護踭(ankle brace),通常需六星期康復。
現階段你"真係好痛.無覺好睡.."大概是剛受傷不久吧，除了吃止痛藥更要RICE治療:
R = Rest 休息
I=Ice冰敷
C=Compression壓力布包腳踝
E=Elevation把脚放高

多受傷後數周仍腫痛，便有可是骨折或靭帶,遲些考慮手術方面，為了檢查靭帶撕裂情度，需骨科醫生檢查及照X光(stress X ray),終極診斷是磁力共振素描(magnetic resonance imaging, or MRI)。

Simple ankle sprain should not have pain more than 2 months!
Tendon injury is extremely unlikely to last that long and seldom rupture (or broken)
Your symptom or pain could be due to some cartilage injury or ligament tear. Otherwise, will not last that long and present with pain.
As a orthopaedic surgeon, I must emphasize the need to have careful examination by specialist followed by appropriate treatment. Ligament or cartilage injury cannot be seen by x-ray so it could not be diagnosed by x-ray.
I would suggest you to seek care by Orthopaedic surgeon, or a physiotherapist with relevant experience in musculoskeletal medicine.
Just wait and see may not be the best interest of your foot or ankle condition.
You can either see private orthopaedic doctor (go to hkdoctors.org to have a look) or ask any doctor to refer you to see Public hospital orthopaedic clinic!
Best wishes!
