Other than autoimmune disease, what can cause chronic joint pain?

Hello doctor,

I have had many years of health problems including severe joint pain, inability to lose weight, chronic fatigue, transient pains, and abdominal pains that seem to come and go in cycles sometimes lasting for days or even months. I have a medical phobia, so have not been to the doctor unless it was an emergency. But over 20 years ago I ended up going to the ER and had several tests. I was told I had lupus, osteoarthritis, PCOS, and thyroid issues. I have tried to treat myself and my pain naturally over the years with a healthy lifestyle and natural aids, but the pain finally became so bad over the last couple of years that I have gone to some appointments. I was referred to a rheumatologist that did blood work and said I was fine except for low vitamin D. I told the new doctor about the early diagnosis and she said it was probably wrong but she would run a blood test anyway. When the test results came back, she said I did not have an autoimmune problem and I was fine except that I had low Vitamin D. I have a copy of the test results that look like there are some problems with me, and based on her reviews and my personal experience with my health, I would very much like a second opinion. I am taking Xanax when needed. Some tests are attached. I have also had an MRI that showed osteitis pubis, fatty liver, and mild bladder inflammation.

Hello doctor,

I have occasional dry eyes and mouth, but not serious. The pain is of varying types, times, and cycles. A lot of pain when first standing in the morning (stabbing pain when my feet first make contact with the floor) and in joints (especially ankles and knees) when I stand. I cycle through phases of mild to severe pain, burning, and numbness in both hands and feet, most often at night. Pain in ankles when not walking that gets more severe without reason while just laying in bed at night and also gets very bad when driving. Other sporadic cycle pains include abdominal pains, all joints stay stiff and painful to some degree. I do not think I am as fatigued in the morning, but I do not do much activity anymore because of the pain levels. I cannot answer the mood changes very well because I have been working with a therapist for anxiety and PTSD and I have been experiencing different reactions than have been typical for my life, but mostly contained to these interactions with little interactions with others. Yes, I am forgetfulness. I have had memory issues to some degree for many years, however, I have become recently worried about an increase in memory issues and I have begun to have trouble locating words. Also, an increase in other connecting thought processing and memory issues. I did not have any infection going on but seem to have chronic inflammation and my CRP is almost always high. The last blood test a couple of weeks ago has a CRP of 22.3 with a normal range of <8.0.
