I have similar aches and pains and the only thing that has really helped in the long-term has been meditating in my recliner. I've had chronic pain for almost ten years and started meditation almost 5 years ago. There's been a dramatic, significant - albeit gradual - reduction in my overall pain. It's still with me, but I feel it getting better every day, provided I spend enough time meditating every day, and cutting back on things that aggravate it: particularly computer use. Playing my Yamaha YPT-230 keyboard can aggravate it, too, but not as much or as quickly.
I got extra impatient and frustrated that my pain wasn't getting better faster, so I tried acupuncture for the first time a few months ago. That helped too. Otherwise, stretching, exercising, walking, Tylenol, Ibuprofen, ben-gay; didn't notice a difference hardly at all with those things. Stretching sometimes helps, but doesn't give any long-term relief like mediation and acupuncture for me.
But at it's worst, I've had numbness, soreness, tightness, tingling, aching, weakness, stinging, and what feels like itching under my skin, and sometimes a bit of sharpness, like a knife in my back. And it's kind of scattered throughout my body, but primarily on my left side. My sister had something similar and was diagnosed with High Blood Calcium. She had some minor procedure done at the Mayo Clinic and she claimed last time I talked with her that her pain went away sometime after the surgery. I didn't catch if it was instant, or how long it took to go away after the surgery. But she too had the symptoms for several years. I might go in sometime to ask a doctor to check me for high blood calcium, but would rather wait a while longer and see if meditation and acupuncture can cure it. I described the meditation to a friend of mine, and he said what I do sounds like biofeedback to him. So anyone interested in trying I'd suggest researching both meditation and biofeedback. The book I primarily used to learn meditation is the Dummies book by Stephen Bodian. Many different forms of meditation outlined in there.
