3 week long ear infection

[Bex0101]

Around 3 weeks ago I developed bad ear pain directly inside my ear and around the back of my ear, I didn’t have a fever but my temp reached around 37.8, the same night the pain was really strong to the point where it would only subside if I was putting pressure on it with an ice pack or hot water bottle, doctor confirmed I had a middle ear infection and prescribed me 5 days of amoxicillin. I took them as directed but after the 5 days I still had ear pain, it was no where near as bad but still prevalent, I spoke with a doctor and she prescribed me 5 days of erythromycin and said it can sometimes take 10 days to clear. I took these antibiotics as directed for the 5 days and after the 5 days were up I still had pain in my ear but it was just mild. I then spoke wirh the doctor again and he said that it could possibly be blocked fluid that cannot drain so to take Sudafed to help, these tablets will be finished tomorrow and my ear pain has only gotten worse, I have been taking ibuprofen and paracetamol as directed alongside this. Is the pain common with the fluid draining or is this something that needs to be seen? Any advice is much appreciated!!!
