Hi John! Welcome to the forum. sorry to hear about your condition. From the picture you have sent and condition you have described, the lesion on the hand seems like Tinea manuum and the condition on nails seems like Tinea unguium to me , they are fungal infection of nails and hands . Antifungal drugs if taken orally and applied topical can help cure the condition. You can go to nearby dermatologist and have simple fungal testing done to confirm the diagnosis and continue with the drugs accordingly. Please feel free to ask any question we will be happy to help you.
