Hyperthyroidism: Your overactive thyroid is the cause. When that has been adequately controlled, your hr will normalize. The Inderal (propranolol) you're taking is the right drug but the dose is very small and clearly too small if your hr is still >100. Stay with your treating doc!

Depdns: For most throat infections, which are usually caused by viruses, you shouldn't take antibiotics at all. But if you've been diagnosed with strep throat, you should take Amoxil (amoxicillin) for the amount of time it was prescribed.

Infection: You have a respiratory/throat infection. Could be viral and could be bacterial best to see a doctor. Other options to help with symptoms include taing elderberry, gargling with salt water or half and half peroxide and mouthwash (do not drink- just gargle) and a warm cloth around neck to hep with lymph glands. Important to rule out strep throat as that will improve with antibiotics.
