I know I have some sort of STD, because I had a rash around my anal area. But After awhile, I have been getting really bad gas, and my stool tends to be loose most of the time right after I eat a meal. My stomach also kind of twitches like a muscle spasm. I used to exercise a lot and it had never happened to me before, but even when I was a teenager I didnt really exercise and ate whatever I wanted and the stomach problems did not effect me at all. I don't exercise now and I do sometimes drink a lot of soda. Is the STD effecting my stomach?

Sometimes my anal area does still itch. I also started to have swollen tonsils but I don't have any pain at all, they just look swollen?

Hello and welcome to eHealth forum!

Worms are the commonest cause of anal itch. Itchy anus can also be due to undigested food like citrus fruits, grapes, certain spices, tomatoes, certain medicines like antibiotics and laxatives and certain drinks like beer, milk, tea, or coffee. IBS, Crohn’s and food intolerance should also be looked into. Anal fissures, hemorrhoids, threadworms can all cause anal itch.

Itch can also be due to irritants like synthetic fiber, toiletries or fungal infection. Genital warts and sores of herpes should also be ruled out. Eczema, dermatitis and fungal infection can also cause this. You need to consult a skin specialist for confirmed diagnosis. Your PCP too can help run basic tests like stool examination and STD swab tests for herpes and genital warts. Hope this helps. Take care!
