If it isn't or wasn't a wart, it could've been a water blister. This sometimes occurs at the start of an eczema outbreak.
can warts spread to inatimate objects (ex. Bags, Furniture)? keyboards?
Hello,
It is very difficult confirming a diagnosis without examination but it can be verruca vulgaris( common wart) or actinic keratosis(small, rough spot occurring on skin that has been chronically exposed to the sun).
Cutaneous viral warts are discrete benign epithelial proliferations caused by the human papillomavirus. Treatment includes salicyclic acid application,curettage and silver nitrate pencils and glutaraldehyde and formaldehyde preparations.
I feel that you should consult a dermatologist and discuss these two possibilities with him. I hope it helps. Take care and God bless.
