Thanks for posting your query
If you are elderly your hip and back pain
might be due to degenerative arthritis
and hot flashes might be a part of menopausal symptoms. I would suggest getting this evaluated by an orthopedician for an accurate diagnosis and appropriate management. You may get the X-ray/MRI
of the area affected under his/her guidance.
I hope this is helpful to you.
