I'm feeling a lot of pain in the upper muscles of my chest, even though I can breathe normally. It feels like there's pressure on my chest. I recently had a chest X-ray, and the doctor said it was normal. I've got acidity, and I'm not sure if that's what's causing this much pain. It sometimes feels like I might fall over, but my blood pressure and sugar levels are normal. I'm really anxious about my health. I've already taken all the reports; CT scan for my brain was normal, and liver, kidney, and thyroid are also fine. I even checked cardio and took a TMT which came back negative. But both the right and left chest muscles are still hurting. What should I do?
