No I don't think just having hpv would give you pain. I had early cancer and didn't have pain. Could you be constipated? It sounds like trapped wind, if I get that sort of pain you're describing I drink some peppermint tea and it really helps.
HPV doesn't have any symptoms & that's why it can only be traced through screening. HPV causes most cell changes & as I understand it, those cell changes eventually cause symptoms. You can read about HPV on Jo's information pages. I am not a doctor & did not have any symptoms when diagnosed with HPV - it was just through routine screening
