Hi doc! I am suffering from hives and angio edema since 1.5 months. Hives coming back for every 3 to 4 days. And these occurs especially on both sides of my stomach and itching in lower legs and sometimes all over body. I doubted on my mosquito net which was installed before 2. 5 months, the dust forms all over it. I removed it. Even after I removed it before 15 days, these hives coming. I used antibiotics (cefpodoxime proxitile before 3 months for fever. Is it was causes hives? I am confusing. And if im taking zyrtec tablet, my head spinning all around. So I used it in half every time. So kindly tell me is this any serious problem? And what is the permanent solution for it? Thanks in advance.
