Hi Brother David glad to see you back on this board, sorry to hear of the problem you are having now. Have you tried "Working Hands Ointment" or "Aquaphor Ointment" on your hands? The "Working Hands" helped my husband heal, and the "Aquaphor" helped my daughter. Their hands were pretty cracked and hurting them a lot. Now they are free from whatever was causing that condition on them. You can find these items over the counter in pharmacies and other stores, which I know I shouldn't mentioned them here. I pray it will helped you too, should you decide to use it.
Lord help Brother David who has been so faithful praying for others on this website, and a faithful servant of yours. Give him a complete healing from whatever is making his hands crack, burn, itch and be so dry. I pray in the mighty name of our Lord, Savior and Healer Jesus Christ amen.
