What Causes Migraine And Diarrhea?

Hi,

i began feeling ill last tues, it started with a headache that turned into a migraine, i went to bed for 2hours to try and sleep it off. but still woke uo feeling the same, i took some nurofen amd went back to bed for another 2hrs, during that time woke up and was sick then went back to bed. woke up without a migraine but still felt very achey and queezy.

wed & thurs felt tired achey, sick and queezy. Fri night was sick again, Sat felt very achey, tired, and a bit queezy. sun felt lots better went out for afternoon, still a bit queezy but much better than before. Mon work up with very bad diarrheoa, pure water (roughly 6 times in 1 hr) then every now and then, couldn't even keep water down. eased off by lunchtime was able to eat the oddcracker. Mon eve ate beans on toast as starving and felt a bit better, tues work up with bad diarrheoa again but feel ok in myself.

I am usually never ill, my husband and son are both fine. we have been trying for a baby since June - had no morning sickness or anything with my son so would not know what this is like. also have PCOS. (not sure if any of this is relevant so thought i'd add it anyway)

Any advice would be great, was gana book a drs appt but worried i wont make it there with out needed the loo!
