Off balance

I’m trying hard not to panic and run to the ER. I went to the doctor about three weeks ago because I felt like the ground was bouncing under me and I was extremely off balance. They said I had fluid in my ears and told me to take Flonase and Claritin. Well I’ve been doing that and I’m still WAY off balance. So I went back to the doctor on Saturday and she said the same thing again. It’s mainly noticeable when I’m looking at my phone or play like a PlayStation game but it’s there other times during the day as well. The thing is I don’t really feel congested in my ears. They are not clogged and I can hear just fine. I’m very scared something else is going on. The only way I can explain it is I feel like I’m moving when I’m sitting still. Like I’m on a boat or a rope bridge or something. I just want to run to the Er to get reassurance that it’s nothing. I’m very scared. Please if you have experienced this please let me know I’m going nuts here. It’s hard to believe allergies could be the culprit.

I know my heart is good. Perfect blood pressure and I had a ekg last October as well as all the blood work on my heart as well. I’ve been to the doctor twice but I still wonder if they are wrong about fluid in my ear and something else is causing this. I don’t know what else would cause this swaying, bouncy, off balance feeling. Im too afraid to google. Im just really scared.
