<s>[INST] Hi, my boyfriend is has this recurring rashes in his chest , neck , nape , arms. He went to a doctor once and they ran tests on him they said it is an allergy . They just prescribed him celestamine. He also used momate one time. According to him momate was effective. But momate was not really prescribed to him. I forgot the name of the other cream.. But he said it did not work as fast and as good as the momate cream. His allergy seems to be triggered by the cold climate. What should we do. He is now suffering from it again. He was not able to get a lot of sleep because of it. He said it is very very itchy. [/INST] From you description it appears a case of urticaria which is usually because of allergy. He should take an antiallergen like cetirizine or Allegra for 4 to 6 weeks and apply a soothing cream like calamine lotion. He should also deform himself with mental 400- 1 tab at night for 2 to 3 days. If the allergy is very troublesome, he may take a short course of steroids orally-something like omnacortil 20 MGM once a day for 5 days, or he may go in for allergy testing. </s>
