i have rescently gone through this experience, and i had no idea what it was. i was sure it was of a spiritual nature though. could have used this thread sooner:>/
for me these "symptoms" lasted for 2 to 4 weeks. and now there are noticeable differences, mostly with energy "sensitivity". (i wasnt even too knowlegeable on kundalini until this thread and one other, but ive now looked into it). so anyway thanks jaycee!! =)
