Hmmm, this is very interesting because I had something similar in the ears and it led to similar problems. I never had the leg problem, but you are over 40... it can be bad circulation and maybe even pre-diabetes. I know the ears can make your legs feel weak and unsteady. I experienced this 1st hand and are still experiencing it today. Also, the shaky feeling is most likely coming from your ears. I think you should have your ears checked and if the Dr. that you’re seeing doesn’t listen to you go see another one. I have anxiety too and the Dr. tried to blame my ear problems on it too. Unfortunately, I trusted his judgment and got severe consequences. I have to do vestibular rehab now, because a viral infection that traveled through my throat to my ear cause an Eustachian tube dysfunction. Usually a low dose steroid will do the trick. Also, remember that keeping active and working out rigorously for 1 or 2 hours can help your body heal faster and compensate for any deficiencies. One more thing, you might want to try taking some vitamin B12 the deficiency of it can lead to similar problems and is especially common in women over 40. Best of luck to you and always make yourself heard, if your body says there is something wrong put the doctors in their place and make them listen. No one knows your body better than you.
