I get really bad blocked ears in the winter, it’s horrible. If it’s just wax sometimes holding a warm drink or something just below your ear on the lawline, or just next to it (not actually on your ear, and not too hot) and very gently moving your jaw can help, don’t overdo it cos you dont wanna damage yourself, but my dad swears by it to loosen wax. Peanut oil seems to work, it’s what most ear drops are made of, but obv not if you have an allergy! Personally I’d go to a normal doctor, he will have a look and tell you if it’s just wax, or an infection, or sinuses, or an alien or whatever. Don’t fill your ears with random over the counter drops unless you know what it is, cos they can damage it further if it’s a different problem.
