I suffer from gerd and gastritis from few years, from few days I have burning stomach, nausea, loss of appetite, I visited doctor recently and he told to go for CT scan for suspect of mass lesion umblical region. After this only I am getting panic attacks at night, anxiety, sudden wakeup with heart palpitation, I am having lower back pain with tailbone pain also, is this anything to be worried about. I have a IBS problem also with cervical spondylosis.
