I had the same problem - bursitis. GP recommend either physio , steroid injection or pain killers and time. I had already had the pain for a long time ( don't like going to GPs) He assured me the pain would eventually go ,( and it did ) I opted for time and ibuprofen. The staircase was a nightmare - one step at a time, getting in and out of the car was difficult too. However be warned! while the hip was still causing me trouble we went away for a weeks holiday. Our apartment had a very low loo and I had difficulty getting up! My left hip was painful so I put extra weight on my right leg and pulled something, left hip is recovered but I compromised my right leg - still causing me pain - muscle pain . Been months now so a trip to GP again I think. I don't repair very well as I age !!
