I have seen many men with sore fingertips. Mostly this was due to some "thing" they were doing in their lives. It is most common in people who use defatting solvents to clean their hands.

Printers (solvents) and masons (lime in cement), often end up with sore fingertips. If you are not cleaning oil or anything else with solvents you might be exposing your fingers to a harsh cleaner, like Fantastik...or an oven cleaner. These have defatting agents in them too. Just doing dishes with the new concentrated DAWN will also defat the skin

People who work in banks can develop reactions to the carbonless carbon paper used for multiple copies of sales receipts, or checks.

If you suspect a defatting agent, you can rehydrate your fingers, with Eucerin original cream at night and wear cotton gloves, called Dermal gloves (available in most pharmacies). This is the typical dermatologist intervention.

Very dry fingertips can also reflect poor fatty acid levels in the diet. Dry heels also occur when people do not eat enough Omega-3 flax oil, which is used to make flexible skin.

Since you don't have this on your feet, I suspect something in your environment is causing this sensitivity.
