From last month I am feeling eye ache and burn with a little head ache while using phone even on low brightness then I stop using it for two days all ok now for five days I feel head ache daily in morning around 10 am and unconsciousness laziness like my head and eyes are filled with a gel. I am eating good I have belly infection too I think it is due to gas. What is it? Even after a running 12 min and exercise I feel sudden weakness (chhakar) for a little moment after that some undigested food come out via vomiting for one or three time.
