There are many reasons why itchy, painful and hard lumps on the heel of the foot can occur, and a common cause is a gout attack. Gout attacks can cause ventilation stones, which can cause localized itching, pain and hard lumps, and can also cause painful restrictions on movement. Gout attacks are mainly caused by high blood uric acid, mainly due to high consumption of high protein foods and alcohol, combined with insufficient exercise, in which case the body will develop gout. Itchy and painful heels with hard lumps may also be rheumatism or rheumatoid arthritis attacks, which are usually aggravated when it is cloudy or cold. Itchy and painful heels with hard lumps may also be caused by skin diseases, such as scleroderma.
