Hello - thanks for asking your question.
You are describing
ribRib cage pain pain and normal x-rays, upper GI, pelvic ultrasound, and echocardiogram.
Always consider cardiac (angina, pericarditis, aneurysm, dissection etc.), pulmonary (pleuritis, pulmonary emboli etc.) and GI (gastritis, dyspepsia etc.) causes - you seem to have undergone the appropriate tests. I will discuss some other causes of chronic chest pain.
Chest wall - Musculoskeletal chest pain is often insidious and persistent, lasting for hours to weeks. It is frequently sharp and localized to a specific area, but may be diffuse and poorly localized. The pain may be positional or exacerbated by deep breathing, turning, or arm movement.
Rheumatic diseases — Involvement of thoracic joints in rheumatic diseases can be associated with musculoskeletal chest wall pain. Examples include rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and fibromyalgia.
Nonrheumatic systemic diseases — Several systemic disorders are characterized by bony involvement that can lead to chest wall pain. Examples include stress fractures, neoplasms, and sickle cell anemia.
Pleuritis/serositis — Pleuritis is an inflammation of the parietal and serous pleura of the lung. Viral pleurisy is a common cause of pleuritic chest pain in young adults. Other causes include autoimmune diseases such as systemic lupus erythematosus or rheumatoid arthritis.
Options that you may want to discuss with your personal physician would be a chest CT and a workup for rheumatological causes of pain. A referral to a rheumatologist or neurologist would be reasonable.
If the pain is determined to be musculoskeletal in origin, a referral to physical therapy may help.
Followup with your personal physician is essential.
