Husband health

So, my 32 year old in shape husband just had a mini stroke and the doctors can't determine why. I have baby #2 on the way and I'm so freaked out about his health. Im having a hard time sleeping or leaving I just want to watch him to make sure he's okay.They put him on high cholesterol medicine (which he does not have) I find odd. He's a super private person and doesn't want me to share with anyone. Just trying not to worry or stress. Anyone else been through something similar?
