I am getting frequent swelling only in my ankle area without much pain, if pressed the skin goes inside..I tried 2 doctors mostly orthopedic considering it was related to leg and bones did xray and few blood test all were okay...my vitamin d was way too below hence doctor recommended uprise d for 8 weeks been taking from 2 weeks there is no change...elevation helps only for sometime then again next morning same issue arises..what can be the case?what is this issue exactly and also which doctor do I consult??I don't want to go to a wrong doctor for diagnosis and prolong it for more time..
