My brother is having issues with his chest. He says he feels dizzy and has migraines a lot. He also has tremors and has difficulty breathing at night. He drinks a lot of water but he barely eats like he should. He has pains from his head to his abdomen.
Thanks for your question on Chat Doctor. In my opinion you should consult neurologist for migraine.  As migraine may be the cause for dizziness. There are many good medicines for migraine are available.  Stress avoidance is must. Eat timely, do not fast, avoid going out in the sun helps in migraine. For breathing issue I advise you chest x-ray and PFT (Pulmonary Function Test) to rule out bronchitis as a cause. If these are normal than stress and anxiety are the causes for breathing problem. So consult neurologist and discuss all these.
