thank you for your question on hcm it may be that you are suffering from generalised dry skin for which you need to use a good moisturiser like venusia Max ( apply it three times day) and also adequately hydrate yourself. but at the time since you have mentioned ankles and legs ,I want to rule out the possibility of varicose veins because it causes severe itching in the ankle and also causes skin bruising. to confirm this you need to get a venous Doppler of the lower limbs and applying a crepe bandage will help.you need to also give some elevation for your limb while sleeping which will provide relief. hope this information was helpful. regards Dr Radhika Lal
