My nose is stuffy, and I have headaches. Is it a chronic sinus infection?

Hi doctor,

I think that I may have a chronic sinus infection. Before four months, I wake up and blew my nose. I had a yellow or greenish mucus with blood in the morning. I did not have any other symptoms except tiredness. I took Advil and seawater nasal spray. It lasted for a couple of weeks. After that, I had a bit of mucus dripping into my throat for a couple of months. After that, I started to have some pressure in my right eyes. I consulted a doctor and he prescribed Amoxiclav for seven days. My eye problem got better and after stopping my medications, I started to feel unwell again. Again, I consulted a doctor and he prescribed me Clarithromycin 500 mg for ten days. After finishing them, I started to have the same problem. I had tiredness, pain in my nose with dizziness. My body temperature was higher than normal. So I consulted a doctor again and she gave me antibiotics. It did not help me. She told me that I have a viral infection and told me to avoid taking dairy products. It has been two weeks now and I am feeling better. But still, I have a stuffy nose in the morning with a bit of yellow mucus. Sometimes, I have headaches with a tingling feeling in the left side of my head. My heart rate is high, especially in the morning. I think that I may have anxiety. I am using Corticosteroid nasal spray and seawater spray. Please advice.
