How are the symptoms of GERD different from strep throat?

Hello doctor,

I am a 20-year-old female with a height of 5 feet and 3 inches and a weight of 132.2772 pounds. I am a nonsmoker and nonalcoholic. Currently, I am taking medication for birth control pills (for acne, 6 years) and Amoxicillin ( last night)

Yesterday I was diagnosed by my doctor with strep throat after telling him I've been suffering from these (major) symptoms:

1. Sore, dry, itchy throat.

2. Difficulty swallowing, feeling as though something is 'stuck' - choking feeling.

3. Swollen uvula and tonsils.

4. Both redness and paleness in the mouth.

As soon as he looked in my mouth, he confirmed the disease, but I accidentally forgot to tell him a few other (minor) symptoms, which include:

1. Occasional, slight heartburn.

2. Stomach aches.

3. Throat and stomach gurgling almost constantly (like when you need to burp but cannot, or your stomach acids are going crazy - indigestion)

Now, I am experiencing vague joint pain (mostly spine) and temporary headaches. I have also noticed they can be better or worse when eating/after certain foods. I try not to self-diagnose, but after researching, I found a disease called GERD, and my other symptoms, along with the throat ones, seem to match it. My doctor gave me antibiotics for a fortnight, but if these symptoms persist beyond two weeks, I think I will revisit him and ask him about GERD (or even a more thorough examination.)

I am just wondering if throat-related symptoms concerning GERD could be misleading for strep throat.

Thank you.
