Hi!
It happens when you suddenly exert yourself with weights.
You need to rest and take anti inflammatory drugs for couple of days and do not lift any weights or do any exercise till then.
If your pain increases or your symptoms worsen we advise an x-ray followed up by Orthopaedician consultation.
Take care!
