Could Pain In Legs Be The Withdrawal Symptom Of Premarin?

I underwent a partial hysterectomy ( removal of uterus and right ovary on March 5, 1982) because of endometriosos. Two years later had right ovary removed because of a benign cyst. I have been taking Premarin 1.25 mg tablets every day for 31 years. I tried to go off of them a couple of timed but suffered mood swings and hot flashes (hot flashes lasted over a year, so I went back on the Premarin) I turn 61 on Tues. and have again gone off the premarin (now for 2 months). So far so good! I do have some pain in my legs and I m wondering if it could have anything to do with stopping the premarin?
