Frustrated- No one knows how you feel- Except you...

Doctor says your fine based on tests, I don't feel fine, it's like no one cares. Been healthy my whole life, am 50 and this feels bad. What should I do next?? Need help please.... Based on all the test results, I feel like an "A" student that is failing..

Duration:
Approximately 6 months (have become slightly more constant), no significant change in pain levels

Most common Symptoms:
Flank/side pain sometimes on left/ sometimes on right, sometimes on both sides. More often when walking, not really impacted by jogging or other exercise- This pain is almost always a semi sharp pain, same whether on left or right side. Not as prevalent in morning, more common as the day goes on. Most common location of pain is left side.
Pain directly under the shoulder blades, less common than the flank pain, sometimes on left/ sometimes on right. This pain is almost always a mild pain, same whether on left or right side. Not as prevalent in morning, more common later in the day.
Midback pain, less common than the flank pain, almost always a “dull” pain that feels deep within the back. More at night, sometimes feels like a burning in the back, but this is rare.
Other symptoms
Headaches (not common, but I don’t typically get headaches very often)
Sensitive nipples (within the last 2 months)
Body tremors and anxiety over “stupid things” like making dinner, my hands will shake
Insomnia- Extreme difficulty sleeping, never been a good sleeper, but the last 6 months, prescribed sleeping pills do not work, melatonin does not work, nothing works, typically takes 1 ½ -2 hours to fall asleep, wake up multiple times during the night

Note: I haven’t lost any weight, but I have been eating more to maintain weight, feels like I am eating at least one extra meal a day. I started working out again about a month ago, and actually have not lost any strength and cardio has slightly improved, which is weird.
Tests Completed (nothing identified a potential cause for these symptoms)
• Lung CT Scan
• CT Abdomen (Upper endoscopy)
• Back X-Rays and MRI’s (Multiple- Lumbar, thoracic, and cervical)
o Note- I tried explaining to the clinic I was pretty certain it was not a back/spinal issue, I can jog, lift weights, rake leaves, mow grass, stacked 5 face cords of fire wood, none of this makes the pain any better or ay worse, it doesn’t really matter what activities I am doing.
• Kidneys- Ultrasound
• Multiple blood tests – All have been within anticipated ranges
