I have some plantar warts being treated by a doctor, a nickel-size
blister formed and is violently painful to touch. This makes it difficult
to wear socks or shoes. Even sleeping requires special care to prevent it
from touching a blanket or the bed.

Bandaging would not help because touching the outside of the bandage is
just as bad as touching it directly. I need something rigid to shield the
sensitive area so that it cannot be touched directly or indirectly.

Can anyone think of something I can buy somewhere (hardware store,
drugstore, craft store...) that is half dome shape with a wide base --
like a full brim hard hat shrunk down to about 2-3 inch diameter? It
would be even better if it is transparent so I can center it properly
when taping it.

I posted to sci.med but I may not get an answer from that ng. Since
people in this ng are better at improvising, perhaps someone could think
of a solution.
Hmmm,
Slurpee cap? Doulbe up to make it rigid.
samething from Tim Horton ice capuccino.
