Water entering the piercing hole when making ghusl

Q: If I get new ear piercings, is ghusl valid if I don't twist or move the ear studs? I am told by the piercer that the new piercing shouldn't be touched or twisted as it affects healing. The ear stud rests against my skin. I'm not sure if it can be classified as so tight that water doesn't reach the skin the ear stud rests on. 

Is ghusl valid without touching the ear studs? If I move it back and forth then it will affect healing or cause it to bleed in the shower.

Toenail reconstruction for a permanently damaged toenail

Q: I am a Muslim woman and have a permanently damaged toenail due to trauma. Although it is not causing physical problems, the appearance of the nail causes me significant embarrassment and distress and affects my confidence. 

I am getting married soon and would like to know whether it is permissible to use a cosmetic toenail reconstruction or similar treatment to restore the appearance of the damaged nail. My intention is not simply beautification, but to conceal and correct a defect that resulted from injury and that causes me considerable emotional distress. 

If such a treatment forms a layer over the nail, how would this affect the validity of wudu? Is there any allowance in this situation, or would it need to be removed for wudu?

Ma'zoor sleeping through an entire salaah period

Q: 

1. If the wudhu of a mazoor person (urine incontinence) sometimes, but not always, lasts through a short salaah period, namely maghrib, will he still be considered a mazoor? 

2. If he accidently sleeps through a salaah period, he will not know whether or not something exited, since movement is little during sleep, it's unlikely something exited, will he still be considered a mazoor?
