thanks for choosing health care magic.sometimes due to injury or prolonged seating this happens ,there could be soft tissue injury
,no bone fracture
so it can not be picked up in x ray.Avoid seating on hard surface,use cushions while seating.You can apply some analgesic
over it and even can do hot fomentation if you are comfortable with.In case of severe pain
sos you can take pain medicines also prescribed by your doctor.
