I’m sorry you have been feeling unwell so long with no answers! I reviewed your photo and lab results. There are several tests that i think should be done in addition. Your TSH is upper limit of normal (< 3) and I would check anti thyroid antibodies to check for Hashimoto’s thyroiditis, an autoimmune condition common in women.
An autoimmune panel that checks for many AI disorders would be helpful. This would include ruling out lupus, mixed connective tissue disease, Sjogrens, and several others. Inflammation markers in the blood (sed rate and CRP) would be helpful in view of the mesenteric adenitis, swollen glands and eye inflammation seen in photo. Skeletal muscle enzymes (CK and aldolase) if you have muscle pain or weakness.
Have you ever had a colonoscopy? That can provide information about the chronic constipation, such as redundant (extra long ) colon or spasm in colon that occurs in irritable bowel syndrome.
The eye inflammation looks like panniculitis, an inflammation of soft tissue (can occur anywhere) but I would also wonder about heliotrope changes associated with dermatomyositis. These are both autoimmune as well. A rheumatologist would be the best physician to check these things but your primary care doctor could as well. You might want to show him/her your post here and the photo.
The prolonged cough with colds and respiratory infections sounds like bronchial spasm, which occurs in people who have a tendency toward asthma or bad allergies. I know this is a lot to digest and you will want to research about these suggestions. The thyroid problem, if present, is easy to treat. I think persistence will pay off and additional blood tests will provide clues. Let us know how this process goes.
