A labral tear is a relatively common injury in young healthy, active patients. In some cases in can be relatively minor, and sometimes the symptoms can be horrible and unbearable. The required treatment is really dictated by the symptoms. Talk to an orthopedic surgeon
for more information.
Firstly, the labrum is a small piece of cartilage that is present in mobile joints (like the hip and shoulder). The cartilage acts like a washer -- protecting the joint from bone rubbing on bone. The labrum can tear either because of significant "wear and tear" (common in older adults) or because of a trauma (common in young athletic patients).
The labrum is not necessarily essential and therefore, what your doctor
will do really depends on (1) how you feel with regards to pain and (2) what you are functionally able to do. If you are in pain, there are multiple treatments like pills or injections. If you are having trouble with mobility, physical therapy to strengthen the surrounding muscles can help. Ultimately, if unberable as you are describing, a surgery
can be done. This is done arthroscopically often -- which means the incision is VERY small.
Talk to an orthopedic surgeon. Surgery can repair it, but is not necessary unless your symptoms are very distressing.
