Just had a partial hysterectomy, but I have PMS anyway. How long before it resolves?

Although I had a partial hysterectomy last week (uterus only, removed lly) I still have PMS worse than I've ever had it before. I know that some symptoms will always be around, but I have the full-fledged "pleasure" of sore & swollen , cramps, irritability & sadness, shooting pains in one ovary... How do I get a message to my brain to shut off the works?? Ouch!
