Since you live in one of the states affected by the new stomach "flu" virus, perhaps you should see your doctor.
It wouldn't hurt to start taking CoQ10. It regulates the heartbeat whether it's fast or slow and can prevent angina. (I take it).
Some people are able to resolve their heartburn/GERD/reflux by taking a Tablespoon of Apple Cider Vinegar in a glass of water everyday. If that doesn't work there are OTCs to try. Sometimes just 1/2 teaspoon of baking soda dissolved in a glass of water will also do the trick. (I now take Dexilant as nothing seemed to work for me.)
Hope this info was helpful.... wishing you the best..
PS Have your potassium and magnesium levels checked. You might need more of these minerals if you are working out regularly.
Does sound very much like you have not got over your cold properly and have now picked up a stomach bug or food poisoning.
Take things easy. If you do not feel like eating that is fine, but do make sure that you drink plenty of juices, water, soup. Keep of all dairy produce while you are ill.
Wash all fruit and veg before you eat them. Make sure that your meat is thoroughly cooked. Wash your hands after using the toilet and before eating any food.
When you say you have had all the tests done. Have you had your breath tested for Helicobacter Pylori and your stools tested to find out which bacteria is causing your illness?
For the constipation, make sure you eat plenty of fresh fruit and veg, drink plenty of water, 2-3 litres of water per day, more if you workout and sweat a lot (don't overdo it though as too much water can be just as dangerous as suffering from dehydration). You already do workouts at the gym so there is no lack of exercise then. Keep of the highly refined foods, junk foods and fizzy drinks.
Hope you feel better soon.
Thank you for your comments. Another day down. No racing heart rate and panic however slight dizziness and cloudiness still persistent. I do not know if they tested for Helicobacter Pylori they may have. I had a gastro who did blood tests, upper endoscopy, colonoscopy. Ultrasound and CT scan of abdomen. This stomach issues I had not found an issue but I could deal with it. This rapid heart rate and panic and dizziness I was hoping was a one time thing but after feeling funny yesterday and strange today I am worried.
The reliable way to check to Helicobacter Pylori is by having a breath test.
Blood tests can give wrong readings. Sometimes a stool sample is used.
Has the doctor checked out your ears and throat for the dizziness?
It does sound very much like you have a viral problem and these can take some time to settle.
Daily life stresses and activities, exercise, drinking coffee and alcohol uses up our Magnesium stores in the body.. Deficiency can cause rapid heart beat, when the heart is beating too fast, it causes dizziness, palpitation, light headedness.. then it causes fright, fear, anxiety..
Please search : Magnesium and rapid heart beat..
and search Magnesium Deficiency.
"The Magnesium Miracle" by Dr Carolyn Dean is one of the best books on Mg. Mg Taureate is the better kind of Mg to take for fast heart beat.
This is cut and paste from a Doctor's site.
Before you consider either surgery or medication, I would recommend my relaxing breath, which is the best method I know to prevent non-threatening episodes of rapid heartbeat such as yours and to stabilize the heart. Here's how:
Sit up, with your back straight (eventually you'll be able to do this exercise in any position).
Place your tongue against the ridge of tissue just behind your upper front teeth and keep it there throughout the exercise.
Exhale completely through your mouth, making a whoosh sound.
Close your mouth and inhale quietly through your nose to a mental count of four.
Hold your breath for a count of seven.
Exhale completely through your mouth, making a whoosh sound to a count of eight.
Repeat this cycle three more times for a total of four breaths.
Try to do this breathing exercise at least twice a day. You can repeat the whole sequence as often as you wish, but don't do it more than four breaths at one time for the first month of practice. This exercise is fairly intense and has a profound effect on the nervous system. Adding more breaths is neither necessary nor better for you.
Once you get the hang of it, do it the moment you feel an episode of tachycardia beginning. In most cases, it will end the arrhythmia promptly.
You also should make these lifestyle changes:
If you smoke, stop.
Limit alcohol consumption.
Avoid caffeine (check any nonprescription drugs you take for caffeine content).
Avoid stimulants in cough and cold medications and any supplements you may take.
Avoid activities that seem to bring on your symptoms.
Take supplemental magnesium: 500 mg twice a day of magnesium citrate, glycinate, or chelate. If this causes a laxative effect, add some calcium citrate to maintain normal bowel function.
So Mg is the possible answer to your top concern.
Combo of Mg, Vit D3 in the 2000 range and calcium foods daily.
Mg is the relaxation mineral, Ca makes muscles contract and Vit D pushes them into the cells where they need to be. Mg will relax the heart.
I'm sorry but you do have to hold off on your Gym activities till you get
the effects from Magnesium. It will take some time, every body is different. but you will be able to tell. Results would be that you will be more relaxed. sleeping soundly..feeling rested.. you could restart Gym activities when you feel more stable-
Give it time. Rest.. and take care.
