Hello My son was diagnosed with strep throat a week ago. He is being treated with penicillian vk 250 mg and ibuprofen. He wasn't getting better so we took him back to emergency a couple of days later and they took a cat scan to see if there was an absecess on his throat. There was none. They gave him fluids and antibotics iv. Friday morning. He hasn't been able to eat a full meal. He says his tounge is irritated feels like it is cut. He has aches and pains and a little numbness on left side of tounge. When he coughs up mucas a little blood comes out not often mostly in the morning. He is depressed because we expected him to feel better with the antibiotics. His throat dosen't hurt as much its his toungue. This stops him from swalloing. Should we continue with penicillian?
