My son finished a 3 day course of antibiotics on Sunday. Today was again given antibiotics for 7 days this time and cream for balantis too. However since earlier he's developed a fever that hit 40. He's had one dose of antibiotics. We were told if he keeps hitting over 39 after 24 hrs to go to a@e but if he goes downhill quicker what would you do? Call 111 for advice? Just feel so helpless
