Hi i am Dr Ahmed Aly prednisone tablets and ointments are usually effective but sometimes eczema extends to 2 weeks in rare cases years its main cause is allergy you may use clean dressings with frequent cleaning without soap and drying it well before putting the ointment then avoid its moisture and avoid humidity as possible, then ask for some antiedematous drugs and try elevating hands and avoid dropping them down to decrease the swolleness . Be patient iam sure it will go away and will return better than before just follow your dermatologist for required dosing of the steroids as they may have some undesirable effects on long term
