Glad your side effects were mild! :)
I had terrible side effects and it literally knocked me off my feet! No ringing in my ears, however I have noticed I have way more wax in them! If it persists though I;d tell the dr's or nurses...it could be tinnitus?
Good to hear feedback on the cooling caps....they aren't available in most clinics (including mine) I have heard it's not pleasant, but hey none of this is pleasant! Hope it helps with the hair loss.
Wishing you all the best with the rest of your treatments.
