Left Top Of Head Pain, Chest Pain, And Right Side

Left top of head pain, chest pain, and right side of belly button pain. Not sure if these are linked, but my DR told me she couldn't find anything for the belly pain after ultrasounds, and that the head pain and chest pain is anxiety/stress enduced. It's been almost a year now and it's getting worse. I'm on 100mg Zoloft which has helped my chest pain.. but now it turned into occasional stabbing pains. The pain in my head isn't really a headache, it's just an annoying dull sometimes painful feeling. Any ideas?
