Dear Dame Edna, I wanted to be called The Grand Poobah and even investigated getting a sceptre and ocelot cape to go with the title ( for state occasions only of course ) but came to the conclusion , after much soul searching, that keeping to a seemingly irreducible sobriquet harking to my Scot roots was the best way to remain memorable , while not offering offence to anyone with the surname Poobah. I think the name Damien is distinguished enough for present company, but if you prefer, Dame Edna, so be it.
Question 2. Probably, but without direct evidence of pathology ( scan ), implicating the hip joint I would be left wondering where my consideration of other cause had left something out. I have not had occasion to confirm any diagnosis of "trochanteric bursitis" in 25 years of careful attention.
I have had occasion to consider there may be "busitis" ( too long spent in public transport ), "biscitis"( over eating choc cookies) and "basitis" ( marginal tone deafness in the lower register brought on by use of headphones). The elusive "bursitis" however I suspect may be on the same level phenomenologically, as the Thylacine.
Hope this helps
