I am suffering from very severe allergic cold that leads to watery running nose and continous sneezing. During this I have itchy eyes, ear, throat. I do have headache with pain near eyebrows region and behind the ears. I literally become restless and sometimes I even go mad because of continuous sneezing. Cetrizine tablet helps me for a temporary relief but this continues again after 2 days. Help me for a permanent relief out of this problem.
