Dear PIGGYPOO. There are some men on this site who do understand & sympathize with your problem, I for one do know how painful Dysmenorrhea can be ( my darling wife now deceased suffered for years before the menopause). You could try Paracetamol interspersed with Codeine ( as you are aware you may take two Paracetamol every six hours ) & also the same dosage of Codeine so two Paracetamol then THREE hours later two Codeine then three hours later two Paracetamol.)You can safely continue this regime for as long as your menstruation lasts. Sqad as he states is not a GP but I think a retired Consultant ( not sure in what field ) but he regularly gives us all very good advice about numerous medical problems. Hope you very soon feel much better sweetie, will be thinking of you in your trauma.
