What could be causing my father's itchy palms and soles of his feet with no skin rash for the past 20 days, which gets worse in the morning and after bathing, given that he has diabetes, low blood pressure, and is currently taking Avil 25?
Itching on your father's palms and soles without a rash, especially worsening after bathing, can be related to dry skin, diabetic nerve changes (neuropathy), or underlying liver or kidney function. Hot water strips the skin's natural oils, which can trigger this worsening. While he is taking Avil (pheniramine), it may only provide temporary relief without addressing the root cause. For comfort, have him bathe in lukewarm water and apply a thick, fragrance-free moisturizer immediately after. Please consult his doctor to check his blood sugar levels, kidney, and liver function through simple blood tests to find the exact cause and ensure his safety.
