I felt the area around the incision, including the great trochanter, for months. The first few weeks could be a bit sharper, then there was kind of muted discomfort at times (but mostly not). For many months it felt itchy occasionally.
The incision is not too big and they stretch it a lot and cut various layers to get down to the hip joint, there is a lot of soft tissue healing to be done underneath and it takes time.
You're very early on in the process, icing should help. I applied it regularly for at least 2-3 months. If you've some bursitis, icing will help anyway.
For me, I couldn't sleep comfortably on the operated side until after 7 months.
Some recommend active release technique, massage etc. Around 5-6 months, my physio suggested massage as there was scar tissue underneath the incision. For a few weeks I did a bit of very gentle traversal massage over the incision, applying some moisturizer cream.
