What would cause an annual outbreak of hives?

• For the past 3 years (coming up on the 4th) I have had a full body outbreak of hives at the beginning of every July. as you can imagine, this makes enjoying the 4th very difficult. I don't eat, expose myself to or do anything different than I normally do, yet they still appear. they last for about 3-4 days getting increasingly worse. They seem to have some sort of track that works them down my extremities until my hands and feet are so swollen and sore that I can't stand to have anything touch them. Then, the next day, they are gone. Antihistimines, oatmeal baths, anti itch creams...I've tried them all without much relief. When I asked my Dr about a possibble cause, all she could say is that I must be allergic to July. Is there anyone out there who might be able to help me before the next outbreak starts?

• Answer:

  That is a very weird condition. I have no clue what might be causing it. There might be some sort of new flower or plant that buds or releases seeds at the beginning of July that you are allergic too. If you haven't seen a doctor, I advise you to. Hope they clear up!
