It Is Rather Embarrassing. I Suffer From A Disorder Related

It is rather embarrassing. I suffer from a disorder related to acne, it causes like carbuncles on and around lymph glan areas( apologies for the spelling in advance) the past few days I have had swelling and uncomfortability around the anus. It near made me cry to go the toilet this morning. I think it may be another of these things as I am forever getting them when my stress is high and immunity is low. But I guess the question is, as I don't know what do haemorrhoids feel like or do?
