Hmm is there anything to prevent me from keeping my other stats?

No. Your health will not change, though. If you had rolled your stats before you had rolled your health, your new Endurance would have been used instead of the hold. However, since you have already used your health re-roll, it won't be affected by any change in your stats.

Other than that, nothing is keeping you from re-rolling.
