I have been having constant brain fog for past two months. Unrefreshing sleep (sleep like a baby 8-9 hours nightly). Been to docs few times now who told me various things viral, bacterial infection, vertigo and lastly as (in my opinion) was only option left GAD. This started after I bought two budgies who I kept in my room (since sold). Can you get a virus from this? I have constant tinitus. Saw an osteopath who told me my lymphatic system was congested and that I am post viral. Can her prognosis be trusted? I am not getting better :( I am taking a range of supplements and eating clean along with daily gentle walks. I am sensitive to light and heat. I also cannot burp properly (small burps which get stuck in throat) My swallow is weakend and feels like my neck is swolen. I realise this is a symptom of GAD however could this be linked to thyroid? I have had generic blood test done no issues. I also get heart palpitations. I realise my symptoms are broad and vague and maybe thats why i cant get to bottom of it but this brain fog is geting me down and i am not sure how to handle it.
