Thanks for writing your query.
It will be helpful if you mention the consistency of your stools.
Bloating in the stomach after meals is common if you are eating fast or talking while eating. This results in swallowing more air along with food resulting in burping. Also avoid gas producing foods like peas, legumes, etc.
I would suggest that you should do de-worming with Albendazole
400 mg at night.
Also take antihistaminic like cetrizine
10 mg once a day. This will help in reducing the skin rash
Antacid like Omeprazole
20 mg along with Domperidone
10 mg will be beneficial in reducing your symptoms.
Avoid spicy and oily foods.
I hope this is helpful to you.
