I agree with Vickie that it is important to train correctly to prevent re-injury or making the problem worse. Almost all medical treatment benifits from maximal conditioning of muscle groups and also stretching to maintain mobility.
Corticosteroid has a bad name in the US and on the internet but if used correctly can be an important diagnostic tool and treatment.
It is not only a painkiller (analgesic) but also an anti-inflammatory. Interestingly it is often used successfully in non-inflammatory conditionss such as cuff tendinosis and tennis/golfers elbow.
The key to steroid is to avoid repeated doses at short interval as they can weaken tissues.
The problem is often the steroids only work temporarily and are then repeated too often causing damage.
Often the condition can get worse in spite of steroid and people often balme the steroid for a deterioration which may have occured anyway.
It is interesting the labral lesion occured suddenly, this is usually the case as is a major cuff tear. Impingement on the other hand often comes after repetitive above shoulder arm use (pay someone else to paint your ceilings)
In summary my advice is try exercises and if non improvement see an expert and have a diagnosis made. Then proceed from least invasive treatments to most invasive until the problem is resolved satisfactorily.
