Does anyone have this type of off balance feeling?

Has anyone experienced a slightly off balance situation? (I’ve worn hearing aids 9 years, I got new hearing aids a month before this problem began) This has been going on for a few months. I am not quite dizzy maybe just a tiny bit now and then. However I feel like I am walking through water at times, or walking on a slightly soft surface. If I walk down the hallway I might take an extra step to the side to get back on track. Occasionally I turn my head quickly and it feels like the inside of my head moved at a different rate than the outside. Also I can go days with no problems and it can last for a short time or most of the day. Sometimes I think my thighs feel a bit weak. Usually when I sit down I feel ok. It is so hard to explain. My PCP referred me to a neurologist, I’m still waiting to get in. I persisted with my ENT she ordered audiology testing which I have this week. She ordered an MRI of my neck too. I can do my daily walk outside so it’s not like I feel like I am going to fall over. It bothers me more with slow movements as you would have walking in your home. Any advice or related experience would be appreciated.
