Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain every medicine has a half life and after that its action dminishes so as you are taking
amoxicillin only once a day its activity diminishes in approximately in 8 hours and then the infection will start increasing again as the resistence has weaned off..
You in case of amoxicillin you should take it atleast 3 times a day..
Tongue is hurting can be due to inflammation of tongue and can be due to inflammation secondary to side effect caused by the medication,
dry mouth, oral infection like
thrush etc..
You should consult an Oral Physician and get evaluated and he can advise you to gargle with numbing mouthwash, take
Ibuprofen for pain and suck ice pops..
Avoid spicy food and drink plenty of water..
Chew sugar free chewing gums.
Hope this information helps..
Thanks and regards.
