I have been experiencing severe internal shaking, which was waking me night. It feels like my whole body is shaking (jaw to legs) but you can't see or feel it on the outside. On top of feeling generally unwell, fatigued, bloated/burping, difficulty eating, heart palpitations, dizziness. This has been on/off for months but really bad for 4 weeks. My GP has run all bloods (vitamin levels, thyroid, adrenaline, hormones, FBC etc), MRI brain, CT neck/head and have had multiple visits to Emergency. Everyone keeps saying my tests are normal. I am starting to believe the shaking is gut related. Interestingly I started taking a probiotic and the shaking has stopped at night. I still feel quite unwell in general and are struggling to eat but the most concerning shaking feeling seemed to go away with introducing a probiotic and gut supplement called bioceuticals intestamine. I am booked in to see a naturopath this week to see if they can provide any input on gut issues and further testing. Also waiting on test results for helicobacter pylori, which i would recommend anyone who has similar symptoms to test for. Posting here in case this information helps someone.
