Permissible and Impermissible actions in Ihraam

Q: I am a 21 year old male who consistently suffers from urinary incontinence. I usually place a piece of tissue in my underwear after urinating just incase some urine drops may come out. 

I plan on one day going for umrah but I am afraid that my condition may cause difficulties especially if I should need to use the toilet whilst in ihraam. How can I possibly solve this issue as a whole? 

I have also read from a previous post that it is permissible to place a bag or wear adult diapers under the ihraam, in such a case does the diaper have to be without any stitching or sewing and how would one secure a bag to ensure it doesn’t fall out?

Q: We came on Umrah with kids and my 6 years 8 months old fell too sick that we have to take him to emergency in Mecca in the state of ihram. 

We treated him and then my wife and my daughter we performed Umrah Alhamdulilah. But due to his sickness we can’t take him for umrah and he had to be taken out of ihram state to take rest. What should I do? Is Damm or Sadqah wajib on me?

Q: I have difficulty with my knees while walking long distances. 

1. While in the state of ihraam, will it permissible for me to wear a knee guard? 

2. In the state of ihraam, can I wear an ankle guard?

Q: I’m a male and suffer from male pattern baldness. As a result I’m wearing a wig to only cover the top part of my head, the rest of my hair is my own. 

1. Am I allowed to wear the wig while I perform Umrah? 

2. If not, and I continue wearing it do I have to pay dumm? 

3. How much is the dumm and what do I need to do?

Q: Can a hernia patient wear underwear in ihraam?

Q: My father has a small problem with old age and urine drops. He says straight after he goes to the toilet, about 5 or 10 mins after, he has some trouble with few drops. Then it subsides. 

He usually uses tissue with his underwear for a few minutes after going to the bathroom in case any drops come out and then discards it a short while later. 

He's concerned with ihraam and how would he manage. 

What would be suggested? Is there an option to wear underwear and pay damm? Or is there any alternative.
