                        I have experienced hives since June and last week I had such a bad episode that my husband had to call 911.  I now carry an EpiPen kit and take Claritin daily.  I had blood work done last week.  If all tests come up negative, do I just let it be?  It was such a scary experience that I'm afraid it will happen again.  I noticed some joint pain prior to this last episode, so I'm inclined to think its something internal.  Anyone with insights or similarities?  I'd appreciate any help.
