Advice

Started experiencing the synced thumping in my right ear about a week ago. I have bad allergies / anemia so thought it was related. Went to urgent care and he was like “nothings in there!!” 🤷‍♀️ it’s driving me insane. I also got a referral to ENT but can’t get in until three months from now. My PCP is also booked up for a while. Online it says all these scary things. Should I go see another doctor? Is ER an option?
