I have had this in the past maybe about 3 or 4 times over the last 5 years maybe.I haven't kept track in
the past when it starts or for how long
i have it, but this time it started in October and i have had it for about 3 weeks now, it seems to be worse at night but some days it does affect me during the day. I have used Benadryl gel which does give it some relief, but I WANT IT TO GO AWAY PERMANATELY! Or at least KNOW WHAT IS CAUSING THIS?
