There may be some problem with your Uke's.
I am the only "finger buster" with documented qualifications to properly assess your insturments
for the specific flaws and infestations that are
definately known to cause this issue.
Please send your ukulele's to me immediately, for evaluation and diagnosis.
Delay may allow the polyestermites to also contaminate other wooden devices in your home.
Imagine if they get loose in the chairs you sit in!
The pain will not be in your fingers.
I have the necessary equipment to eliminate and rid the world of this plague.
