Hi @Flower88. Sounds similar to what I experience. Do you get a hot flush with it, heart palpatations?
It used to be much worse for me, but I have done alot of research over the years, as I wasn't able to sleep much at all. Was waking often with the symptoms.
When we are under alot of stress for a long time, it can affect our gut, causing things like IBS and gut inflammation. I finally realized that perhaps the gut inflammation was causing the hot flush (it's not hormonal for me), which then caused the heart palpatations and the unusual feeling in my head (similar to what you described).
It took me ages to figure out what foods were causing all this. I have found that when I don't eat certain foods, the symptoms go or lessen. They are foods that I can't tolerate, such as nuts, oats and the list is long. We are all different, so it could be other foods for you.
It sounds strange that gut inflammation can cause these symptoms, but through trial and error, eliminating the foods has helped me alot. When I eat the foods that I shouldn't and eat them often, I go back to not sleeping, because of all the awful symptoms. It's amazing really.
I can't be sure that this is the case with you, @Flower88. It could be something different, but I just thought I'd mention my experience. I look back at how bad I used to feel with it all, at night time especially and I am so grateful that I figured out what the real problem was. (After asking several doctors). Thankfully, I didn't take the meds they recommended for it, as they would not have helped me.
I hope that this helps you @Flower88.
I look forward to hearing if you have the other symptoms as well.
I understand how awful it is to experience this at night time, as you feel so alone. But good you have this forum to chat to people. Hope it helps.
