If the doctor finds nothing, you might want to keep going until something is found. Might as well get your thyroid checked while you're at it. If the doctor keeps failing, try a naturopath. They heal you as opposed to just dispensing drugs that cover symptoms. Though, it would involve life changes. Well worth it if you're very sick, and it would also mean you won't be sick later on in life.
Did you tell your doctor how these symptoms appeared after eating the Chinese food? If you have new symptoms like palpitations you should definitely see a doctor as you have new things to tell and get checked for.
Gas, bloating, fatigue can all easily be caused by bad diet. In fact, just about every single disease is caused, exacerbated, or mis-prevented by a bad diet, even cancer.
One of the quickest fixes is to improve digestion. This can be accomplished among other things, by taking probiotics. Probiotics are beneficial bacteria which will improve digestion, help you assimilate nutrition, improve immune function, keep bad bacteria/fungi/yeast in check, etc. You can find it at health stores. Look for enteric coated, multi-strain, high count. You could also look into Spectra 12. Contains many strains as well as other whole food sources which are great for health. Eating fermented foods could help too, such as yogurt, kefir, saurkraut, etc. However, if it's pasteurized there's really no point. Non-pasteurized could be found at health stores, Whole Foods, or on the internet.
General diet guideline that I'll copy and past from another thread I just posted in...
""Healthy comes from eating the right foods and avoiding the wrong ones. Eating 9-12 servings (based on body size. women generally need less) of vegetables and fruit everyday, mostly raw and mostly organic (especially apples, strawberries, cucumbers, celery, peaches, etc. As they have high amounts of pesti/herbicides). Low on grains, but the seeds, nuts, grains you do eat should be soaked, sprouted, or fermented. If you eat dairy, it should be non-pasteurized and raw and organic. Meats should be organic. Including fermented foods is good, and/or probiotic supplements. Also a natural multi-vit/mineral, as well as an omega 3 supplement. Avoid refined sugar, processed flours, hydrogenated oils, and overall any processed foods. Steaming vegetables is the best way to cook them, and oils should generally not be cooked with. Not that oils are bad, but heating them is. Don't overcook meat, or anything for that matter.
To top it off add an exercise routine. Including cardio as well as weight training. Weight training isn't just for muscles, it's for health and strong bones.""
I could write a million words getting more specific, but that's a guideline you can look into more. It's hard because corporations and media make it sound so easy. Stay away from red meat, wrong. Whole Grains good, not so right. Eating the least amount of processed is the best. It's complicated because processed means so much. Meat isn't bad for you, it's the way meat is made. Injecting hormones, antibiotics, feeding them unnatural diets of corn and grains, fattening them up, etc. Pasture raised, organic meat is good for you and part of healthy human societies.
Pasteurized, processed, preserved, refined = bad. MSG, Hydrogenated Oils, refined sugar, white flour, basic table salt, caffeine, artificial sweeteners = bad.
