Hi Pink68,
One of my first premenopausal symptom, as well as virginal atrophy.
I've read that if you had back problems in the past they will get worse with menopause. I also get upper back pain, rib pain, chest pain, and any other part of the body you can think of.
I've been to the doctor, had X-rays, blood test, MRI, and seen a rheumatologist.
The best thing you can do is Pilates, as my doctor says, strong core, strong back. I went to Pilates classes once a week for 6 months. Took note of whenever we did core exercises. For the last 6 years I get out of bed and do 15 minutes of Pilates everyday. I definitely feel the difference. And my abs look amazing too.
