Thanks for writing to H.C.M. for your query.
I have gone through your query and observe that your symptoms get finished with levocetrizie this indicates that they are allergic, and second important thing is that these allergic problems have developed only from last few weeks. Are you recollect your memory that any new item you have incorporated in your life as any new variety of cosmetic, any soap, tooth paste or any food items may be cooking oil etc. because for allergic reaction
there should be an allergen. and once allergen is identified than avoidance of allergen is the best management for allergic disorder.
If you are not able to identify any allergen than try to know weather your problem is seasional or perineal (remains whole year). If it is seasional than you can use any anti allergic for about 21 days.On the other hand if it is perineal allergy
than you cn follow skin test by this allergen can be identified and than after your body will be desenstise by suitable vaccine
I hope your query is explained .
