Regrettably that's the problem, but see the National Eczema Society website for guidance on using corticosteroid creams, emollients and what is sometimes called 'weekend therapy'.
I would ask to be referred to a dermatologist, sounds very similar to how I started and 3 years later I have it confirmed that I have Lichen Planus. After trying numerous steroid creams none of which have worked, I now have PUVA light therapy twice a week and currently on steroid tablets moving to another tablet methotrexate in 2 weeks time which will make me immuno suppressed. Had I been more vociferous with my GP about seeing a dermatologist perhaps I would not have got to this stage, so I would advise asking to be referred. I am not saying it will be the same condition but as you have already had it a year, it certainly needs to be looked at for your peace of mind.
It sounds like you are treating a symptom and the cause may be something you have a contact allergy too. If you do not find and remove the cause/trigger, the symptom will return each time you stop treatment.
