I have skin urticaria condition since 5 yrs. I have consulted doc on this 5 years back and got to know that this condition is chronic skin urticaria. Took fexova 180 ( fexofenadine) tab for 2+ years, 1 daily. Took secondary advice from another doc after 2+ years, changed this medicine to lecopM (levocetrizine & montulukast) tab 1 daily, taking this since 3 years..Condition comes under control only when i take these pills. It appears again on the second day if i stop taking this. However, the condition isn't that much which it was 5 years back. Frustrated with this condition now and want to know how long i need to take these pills. Requesting for your kind advise on why this condition came so suddenly, what I need to do and how will this go off permanently which would relax me mentally and physically.
