age: 29, weight: 53kg, height: 161cm, medical history: depression for many years, secondary amenorrhea for the past 7 years (on-going) I am having knee problems for the past 2 years. No pain, but sensation with every step that I take. Went for MRI scan, took X-rays, saw chiropractor , orthopaedic specialist, rheumatologist , physiotherapist. Still don t know what is the root problem of my knee problem. There was no major accident or fall. Before my knee problem, I jogged every single day for 1 hour for about 4 years. Also, I wore shoes that were too small for me. Might these be the cause of my knee problem?
