I get phlegm in my throat with irritation for a long period. What could be the cause?

Hello doctor,

I got a few inquiries about my current situation. I was suffering from this white phlegm in my throat for six months that bothers me, especially when sleeping. I consulted an ENT online who said that I was suffering from laryngopharyngeal reflux, and she prescribed me antacids and PPI for two weeks. I took Tums and Nexium for two weeks. It helps, but it does not eradicate. I met a doctor, and he said that what I have is not reflux but an allergy due to the weather. So, I took Claritin once a day for a week. It helps, but the phlegm is still there. Until now, my throat still has white phlegm and bothers me at night time. What illness is this? I am suffering this for about six or seven months.

When I arrived in my hometown last month, I got a wound on my right foot. It is itchy, and I was scratching the sides of the wound. Eventually, there was a small bruise that forms a circle and turns to the wound then appears red with yellow pus. I cleaned it with lukewarm water and applied the Betadine solution afterward. The wounds dry up, but there is still a little pus in it. Somebody told me (not a doctor) not to eat chicken and pork because these foods could trigger it, especially that it is itchy and what I have is not an ordinary wound. But last night, I unintentionally ate chicken and hours passed after eating, my feet were itchy, and this morning I noticed rashes like thing spreading in my legs and arms. It is a tiny red rash. It is itchy too. Is this an allergy, or is there something wrong in my blood?

I also have this little bruise on my tongue's right side and two circle spots in my tongue. The bruise in my tongue is a little bit painful. I do not know what this is, but please advise. I am 33 years old.

Thank you doctor,

I need a valid prescription to present to the pharmacy, especially for this Augmentin (antibiotic), so that I will be able to purchase it from the pharmacy. Pantop brand for heartburn or acid reflux is not available here in our place. Would it be fine to ask for a replacement for it? Esomeprazole, omeprazole, etc. Are Cetrizine and Cetirizine the same? Beclomethasone and Clotrimazole - is this refers to one name of cream or two cream names. Please advise.
