Split Ends
Split finger tips and thumbs are unfortunately part of playing. It sucks and there is really nothing you can do except wait for them to heal.
I struggle with this as it delays my practice schedule, but I try to use the time in other ways like writing meaningless blog posts and posting random irrelevant crap on social media.
A more productive person would just practice things that don't need thumbs, like singing or mixing recorded demo tunes. That person might also benefit from updating website content or making list of potential venues for future gig dates.
