I too have had these internal tremors mostly in my lower legs and feet now for about 2 months now. Its every day, all day sometimes it seems as if its going away but then it comes right back, Sometimes its in my upper chest but not often .Ive have Tinnitus also for about 5 years since having these Tremors the pitch has changed. My primary treats this as if its nothing, no mentioning of sending me to a neurologist but said he believes its a form of anxiety because I recently lost my husband due to Covid and I had long Covid as well last year. He prescribed me Zoloft which is a anti depressant but Im afraid to take it because one of the side effects in taking Zoloft is Tremors. Go figure.

Do you have them at the day time or just when you are falling asleep and waking up?

Did you ever find a diagnosis or treatment ?

Have you ever been exposed to ticks I was exposed as a young child in the Adirondack Mountains I know I had ticks on me and at that time antibiotics were not given I have a vibration feeling often in my body which seems to make me feel weak at the same time. I've experienced this twice in the past and was diagnosed with Lyme disease it will show up in the blood when a Lyme test is given . Thank God intravenous antibiotics were finally given. oral antibiotics simply don't work I got over it in about 6 weeks each time and was fine for many years until it seems it comes back especially it seems if I am overly tired. I have this at the present time and will be looking for a doctor to put me back on intravenous antibiotics. I can't believe how ignorant many doctors are about Lyme disease.

I have exploding head and tinnitus. I am starting to try to be diagnosed. This is hard so be assured you are not alone. I can't figure out what is happening. I too am told relax. I feel that there is a diagnosis relating to other issues.
