Hi...
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns...
As per your complain heartburn and burning in the throat seems to be most probably due to Acid reflux causing inflammation in the food pipe and throat and there is burning..
As far as burning during urination is concerned the most common causes for it can be
Urinary Tract Infection and you should get a urone culture and sensitivity done to rule out for the exact bacteria causing infection and antibiotics can be advised accordingly if required..
You should
consult a Gastroenterologist and get evaluated and he can also advise you to get an Endoscopy done to confirm the cause.
For acid reflux you can be advised to take
Proton pump inhibitor like
Pantoprazole or Omeprazole.
Take antacid like
Milk of Magnesia before meals, take light frequent meals and avoid spicy, heavy and acidic foods..
If you are obese loose some weight..
Drink plenty of water and take more of Probiotics in diet..
Take your dinner atleast 2 hours before sleeping.
Keep your head slightly raised as compared to feet while sleeping and recline in left lateral position..
For Burning during urination drink plenty of water and fluids, wear loose fitting and cotton undergarments and maintain a good personal hygiene..
After confirmation of infection doctor may advice you antibiotics like
Nitrofurantoin,
norfloxacin etc..
Hope this information helps..
Thanks and regards.
