Babs,
Take one day at a time and do go see your General Physician or PCP. Mine took over the pain management and I had to go see him every 30 days for more medication. You do need it, and you also must be aware the Doctors are being monitored regarding how much pain medication they prescribe to patients due to others over prescribing......
If you are not getting the relief you require, be sure to ask for more medication.
I started walking and did a mile and a half loop yesterday. I hope to gradually increase my distance this spring and summer. Hopefully, it will increase my stamina and help me lose some of the extra weight I am carrying.
Keep exercising, get as much rest as you can at night (even move from your bed to somewhere else if you have insomnia as it helps get you back to sleep).
Best,
