Hi, Welcome to icliniq.com. As per your history the problem has been long standing for around five months or more. I advise you to visit a nearest physiotherapist to start and continue knee physiotherapy. Abstain from sporting activity for a few weeks. If after around four to six weeks your symptoms do not improve, then my advice is to go for MRI of the affected knee for possible ligaments or meniscal lesion like cysts or any synovial changes.
Hi,Welcome to icliniq.com.No, this is not a calcium deficiency. Probably, it is prepatellar bursitis. The symptoms of calcium deficiency will not be confined to one knee and it is unusual in young persons.Thank you.
