Knee probelm from 6 mont. Knee it pains.

Hello there,,,,well if you have pain since 6 months then definately you need a proper assessment of your knee so as to find out the cause for your nagging problem...do you recollect a history of fall or trauma to your knee 6 months back?... have you stressed your knee that time like overexerting during sports or gone for trekking or something like that?.... well right now what you need to do is get an x ray of your knee done in AP & flexed Lat view ,also get your Vit D and sr calcium levels checked...with the latest findings you could vist a musculoskeletal physio or an orthopadecian and get a proper opinion regarding it....for the time being if it hurts on activity avoid sternous activity and wear a patellar knee cap for stability and relief. Regards & take care.
