Hi
Welcome to the MedHelp forum!
Yes please consult a doctor immediately to rule out heart causes and gastric reflux as a cause. You also need to get examined to rule out a few things such as low blood pressure, postural hypotension, cervical spinal nerve compression, hypoglycemia, severe anemia, an underactive thyroid (called hypothyroidism), overactive thyroid (called hyperthyroidism), adrenal insufficiency (called Addison's disease), and internal ear infections.
Hope this helps. Take care!
You may want to ask your doctor about heart arrythmias. I could never figure out what mine was and I could never get it to happen at the doctor's office, but it kept getting more frequent until they were able to diagnose it. I thought it was allergies but it wasn't. There are lots of great treatments available and I haven't had any problems now for ten years. Good luck!
Yes you should see a physician. Shortness of breath and tightness is the chest can often just be associated with anxiety, but because you get dizzy and have trouble standing--and so often, it is best to be sure there is nothing more serious going on. Two or three times a month is still too often to experience this extreme dizziness. If you're experiencing it four or five times a day, your body is trying to tell you something.
All the best,
