Hi, !
I'll be honest; I have never heard of using amoxicillin to treat fatigue. In fact, amoxicillin is know as an antibiotic that can actually increase a person's feelings of tiredness. Also, antibiotics do not directly relieve pain, but as they clear up the infection (which is what they are generally prescribed to treat), a person may notice a decrease in their pain levels, if the pain was caused by the infection.
Did someone suggest trying amoxicillin to you?
