Had steroid injections in both knees and both hips. Four weeks later steroid injection in one shoulder. I'm a steroid machine! Shortly after, began interruptions 2-3 times nightly with painful leg cramps. Cramps sometimes occur in day along with hand cramps. I do stay hydrated and take high doses of magnesium (per my internist instructions) and calcium and eat 2 or 3 bananas a week.
