Hi @MsFrog I have had Shingles twice, once many years ago before the medication was available that helps prevent it getting any worse. The second time I got it, 9 years ago, at a time of great stress to me, I was able to have the antiviral medicine, I think mine was Aciclovir, and I only felt mildly ill with the Shingles compared to the first time. If you have not had an antiviral I have no idea how you are still doing anything?
Shingles is the most painful and debilitating acute illness I have ever had, probably because it is an illness that it's very own raison d'être is to stamp on and squeeze a nerve until it is almost screaming in pain! Therefore the first time it erupted (it lies dormant in our bodies after having had Chicken Pox) I was given extremely strong painkillers by my GP, by both injection and orally. I didn't ask what they were at the time as I was so out of it, but looking back now I think that they were probably both Poppy based.
The painkillers made me sleep most of the time, I even had to use a commode by my bed as I couldn't have made it as far as the bathroom even though I was usually a healthy and strong teenager, because I just felt so weak - luckily my Mum still had a commode from when my Grandmother was ill. The upside was that I had the most amazing dreams 😊
I know that when I got Shingles the second time, that after having the antiviral tablets I didn't really get any pain. I did feel washed out, very drained, but thank goodness no pain. Whether you have had the antiviral medication or not OP you really do need to be resting, you may actually prolong your full recovery by quite a long time if you don't take it easy now. I presume that your Dr has told you that your children should not get near enough to you to catch Chicken Pox (if they have not already had it) from any weeping spots or blisters. That goes treble for your husband if he has never had Chicken Pox, as Chicken Pox can be much worse for him.
I didn't like my spots to be covered up, but if your husband or children are susceptible to Chicken Pox then it would probably be wise to cover your spots/blisters up with a non "sticky" - lint free, bandage, if you cannot guarantee that they won't come into contact with anything (eg sheets, nightwear, flannels or towels, that you may have used). Of course you should keep your flannels and towels in your own room whilst you are still infectious.
Anyway, until your last spot has dried up, you really should be keeping out of the way, and resting. Hopefully, if your husband has to cope on his own with the children, it will start to massively decrease his fear of not being able to cope (and therefore his irritableness), and increase his self-confidence. Then if you are incapable another time, keep out of it again, and that should help reinforce his self-confidence. Whenever you talk with him about things like this, try to sound like there are no worries, you trust him to be able to cope - without actually saying those words!
I hope you feel better very soon @MsFrog, and please try to let your husband's moods wash over you whilst you are ill. 💐💐💐
