Whats wrong with me (strange symptoms)?!

I have been recently experiencly some strainer and random symptoms.


For the last week I have had diahorea along with bad stomach pains. I have had very itchy arches on the back of my thighs and a horrible feeling of sickness and gagging after eating.

Today I have been experiencing itching all over along with runny nose and sneezing.

Please help, I know it sounds weird but it's really effecting me.

Thanks.
