I ve been feeling nauseous for over five weeks now. All my doctor said was that it was probably a virus, but no one I know had it, and I rarely leave the house anyways. I have a fish tank though and it had a breakout of Blue Green Algae, and I was wondering if that might be the cause. I cant read anything without wanting to throw up, and some TV shows that have a shaky camera make me sick too. I m 20 year old female, and I m not pregnant. I ve been taking ginger gravol but it only helps for a little while, and it s getting expensive. any help would be great! Thanks.
