Hello,
Thanks for the query to H.C.M. Forum.
You mentioned that GERD is there ,this is right and you are taking
omeprazole 20 twice in day.
But in my point of view ,this is a not complete treatment as you are also taking Ranitidine 150 mg thrice in day.
Here we will discuss first about the hyper acidity and its reason.
This may be a
peptic ulcer disease or Haitus hernia.
Diagnosis can be confirmed by upper G I endoscopy.
As you mentioned that you sleep in sitting position , this is a good thing ,but severity of disease can be judged .
Also avoid alcohol, caffeine , junk ,greasy food.
Please don't take any type of tension or stress.
Consult a gastroenterologist and get hid opinion and treatment.
In my practical life I have seen that main cause of gastritis is TENSION.
For
thyroid nodule consult a thyroid specialist and get his opinion.
However it seems that this is simple case of enlargement of thyroid not any cancer.
Good luck.
Dr. HET.
