[|Human|] Dear Doctor, I am suffering from large red patches appear and dissapear in an holf an hour like that since from last 3 years while in that condition feel itching in hand , stomach and other parts of the body but I under gone so many tests but the Doctors say no problem in body and it is due to some stress and some psychiatric probem and in IGE level seems to be high range in value means shows 519, for this I took tablets one year back but still not recovered. Please suggest how to proceed for the next treatment Thanks and Regards BABU.B
[|AI|]  Hello, Your condition is called urticaria and most people (80%) do NOT have allergies although the raised IGE level would suggest an underlying allergy. Stress compounds the problem and causes the lesions to last longer but is not the cause. You will need tests such as full blood count, iron levels, CRP, ANA, TSH fT4, TPO antibodies to exclude a secondary cause. Long acting antihistamines such as Allegra 180 mg plus cetirizine 10 mg in the evening for 4 weeks is recommended. For an acute generalized eruption that does not respond to antihistamines, you will need a short course of steroids (Omnacortil 40 or Prednisolone 40 mg once daily after food for 5 days) as the last resort. I hope this helps. Thanks.
