Eustachian tube dys. Or Eardrum rupture?

Initial Symptoms: On Thursday, 6th March, I experienced a fever of 101.7°F. I took Dolo, which brought my temperature back to normal. After the fever subsided, I developed a sore throat with some cough. The cough was particularly severe on the night of Saturday, 9th March. Ear Symptoms: On Monday, 10th March, I started experiencing twitching sensations in my left ear. By the evening, this escalated into severe ear pain. Current Condition (Sunday, 16th March): My left ear is still blocked, and I hear a muffled voice from that ear. I still have some cough and mucus. Major relief in cold as I am coughing a lot less now but my ear is giving me issues, could it be a Eustachian tube dysfunction or a eardrum rupture? Please advise on the next steps.
