Hey Kevin, Just came back to the guitar after 30 years and yeah KNOW what you mean

.
First of all if your guitar has a lot of high action your fingers WILL be sore no matter what but if not 3 things you can do
1. Practice for at least 10 min each day
2. Soak your fingers in 1/2 cup of apple cider vinegar ( stinky)
3. get some sea salt and disolve it in hot water (keep it handy and soak for 2-3 minutes each day.
I am trying NEWSKIN ( get at (*) and its like liquid bandaids ) and painting it on my fingers ( and yeah it helps

) but we still gotta get those calluses growing to prevent that pain buddy

Good luck and hope this helps
