Hi, the muscle aches were / are my biggest thing. Mine are now soooooo much better though. I was misdiagnosed with fibromyalgia, tendinitis (my pain was elbow too) etc prior to peri diagnosis by a specialist.
I have just started estrogel and will be starting testosterone shortly. I can't advise on that I'm afraid with your medical history, but if you take a look on Menopause Doctor.com there is also info on there. I think a meno specialist is the best idea.
I do yoga stretches morning and night, go on a 4 mile hike most days, do 1kg free weight, have Epsom salt foot/baths (cheap in bulk off Amazon). Regular full body massages help (your other half can have a go at that). Hot water bottles are good on targeted areas. Celafen cream is good for neck and shoulder aches. I take an occasional paracetamol as they are the gentlest painkiller.
Honestly though, being active is the absolute best thing and after the initial phase of it hurting a bit more you will reap the benefits. If you check out the Arthritis U.K. Website they have lots of great easy stretches that are very similar to my yoga ones.
My arches had collapsed around the same time which caused lots of back / hip pain (again undiagnosed by gp) so it might be worth going to a podiatrist too to get your feet checked just to rule it out.
I used to teach so I know how heavy the loads are that you are expected to carry. Plus changing room layouts, sorting equipment etc, I would not be able to cope with that anymore I don't think. Maybe have a chat with your employer about resources to help you (maybe one of those pull bag things). There is info on Menopause Doctor that you can give to you employer.
I hope some of this helps x
