Unwell for over a month

Patient: Since the beginning of November i have been unwell. Started with the worst headache i’ve ever had that made me sick and left me with no energy for a few days. On the lead up to this i had white ulcers on roof of mouth near my throat. Then i got all congested with sore throat, blocked nose, sore and blocked ears. Everytime i blew my nose i got really dizzy. Felt really light headed and sick. Throat has at times been very achy and i’ve had a temperature and chills plus feeling very sick and lack of appetite. My asthma has now became pretty bad and i have a sore upper back and swollen glands. Been off work twice for total of 5 days and due to return tomorrow after holidays but feel really unwell and have been very tired this whole time also. Is this the flu?
