What other issues could lead to such symptoms,
The short version: the retrieved evidence points to rotator cuff problems, cervical spine issues, and fibromyalgia as the main alternatives to thyroid disease for clavicle and shoulder pain.
The strongest alternative is rotator cuff disease. Exercise programs improve pain and disability in rotator cuff tendinopathy [1], and thoracic spinal manipulation reduced shoulder pain in patients with the same condition [2]. Diabetes is relevant here: one study found no significant difference in rotator cuff tears between diabetic and non-diabetic patients after adjusting for age [3], while a 2025 study found ultrasound detects shoulder abnormalities in diabetic patients with about 87% sensitivity and 91% specificity [4].
Cervical spine problems can masquerade as shoulder pain. A 2020 study found 31% of patients with suprascapular neuropathy also had cervical radiculopathy, a "double crush" pattern [5]. A 2026 study found infraspinatus tenderness and painful resisted external rotation were significantly associated with pain severity in cervical radiculopathy [7]. Even a rare Tarlov cyst chain from C2 to T1 caused left shoulder pain in one case [6].
Fibromyalgia is another possibility. Chronic widespread pain is its defining symptom but not unique to it [8]. One 2026 study found 26.7% of critical care nurses screened positive for fibromyalgia, with high stress and poor sleep as predictors [9]. Vitamin D deficiency is more common in chronic widespread pain (odds ratio 1.63) [10].
| Condition | Key finding | Source |
|---|---|---|
| Rotator cuff disease | Exercise improves pain | [1] |
| Cervical radiculopathy | 31% had double crush | [5] |
| Fibromyalgia | 26.7% prevalence in nurses | [9] |
| Vitamin D deficiency | OR 1.63 for widespread pain | [10] |
The retrieval did not surface studies on inflammatory conditions like polymyalgia rheumatica or autoimmune myositis, which can also cause bilateral shoulder girdle pain. Those remain possibilities worth discussing with a clinician.
My call: rotator cuff disease, cervical radiculopathy, and fibromyalgia are all credible alternatives to thyroid disease for your symptoms. Confidence: moderate.

Comparison of three types of exercise in the treatment of rotator cuff tendinopathy/shoulder impingement syndrome: A randomized controlled trial
This study compares the efficacy of three different exercise programs for treating rotator cuff tendinopathy/shoulder impingement syndrome, finding that all programs resulted in significant improvements in pain and disability without any one approach being superior.

Shoulder Double Crush Syndrome: A Retrospective Study of Patients With Concomitant Suprascapular Neuropathy and Cervical Radiculopathy
In 100 patients with EMG-confirmed suprascapular neuropathy having arthroscopic release, 31% had shoulder double crush; these patients showed more median neuropathy and smaller side-to-side CMAP amplitude differences but similar pain and strength improvement.
