Thanks for posting your query.
I can understand your concern.
This seems to be a case of palmoplantar psoriasis. In this condition there are lots of fissures and hardened skin and there is also a lot of bleeding from these fissures.
I would recommend application of mupirocin cream mixed with clobetasol cream twice a day on the affected areas. You will need a prescription for these creams. Also in case these medications do not help, it would be best to visit your dermatologist who might start you on oral medications as required.A review of the lesions after a week of using these creams would be necessary.
In case of itching, she can take an anti histamine like claritin.
Please let me know if you have any queries.
