Hi, I Am A 57 Year Old Female. Most Of

Hi,
I am a 57 year old female. Most of the muscles in my back are rock hard. I used to have a lot of pain.
Now I have some pain and much fatigue. I am an artist and doing work at the easel has become almost impossible, house work is down to only what has to be done. A few years ago a Dr. gave me some muscle relaxants ( they knock me on my ass and constipate badly) so alcohol on occasion is helpful.
I have started seeing someone for deep tissue massage, for 7 times now in 3 weeks. I am suspecting that this will end up being helpful but not a cure because the why is not addressed. What kind of Doctor should I go to and what are the right questions to ask.?
How do I find the right kind of exercise?
