Feeling sick, tired, tight stomach

Hi,

For the past few days I have been feeling extremely sick and tired all the time. I feel really weird and light headed/dizzy, one minute I'm hot, the next I'm freezing. I also keep feeling a tightness in my chest and under my ribs and I wake up with a bad headache that doesn't seem to go away. My doctor prescribed me Propropranol last week as I have anxiety, however I have had these before and they have never made me feel this way. Please can someone help as I am getting quite worried?

Thank you

I have felt this way before.  You might be dealing with constipation, food allergies, or maybe gallbladder disease.  Hard for me to sort out because I had all of those.
