Treatment of tendon injuries is largely conservative. Use of non-steroidal anti-inflammatory drugs (NSAIDs), rest, and gradual return to exercise is a common therapy. Resting assists in the prevention of further damage to the tendon. Ice, compression and elevation are also frequently recommended. Physical therapy , occupational therapy , orthotics or braces may also be useful. Initial recovery is typically within 2 to 3 days and full recovery is within 3 to 6 months.  Tendinosis occurs as the acute phase of healing has ended (6–8 weeks) but has left the area insufficiently healed. Treatment of tendinitis helps reduce some of the risks of developing tendinosis, which takes longer to heal.
I too am in the same stage as you - I am off to see two hip surgeons on the 7th and 8th Dec to take their advice (8th is a second opinion and he is a research surgeon). I dont think this steroid is going to last at all, and my surgeon did say they don't always work if that gives you any comfort, and I too share your worries and am glued to all of these discussions! I know with my own scan the MRI didn't show the osteoarthritis but my Xray did (and this is common apparently) - I have some tasty osteocytes . spurs etc - have you had this done? I had friends winding me up about the steroid not working as much as I had hoped but draw comfort from my scan (and my 1st surgeon's comments) if that is of help.
