Eleise, thanks for sharing your story. It brought a giggle out of me for the first time since my son crossed on 06/18/09.
Never heard of decongestant nasal sprays working for that type of remedy, but it makes sense. Benadryl after all is a decongestant, antihistimine. My home made remedy for bites, stings, burns, scrapes, etc... is Lavender essential oil. I keep a small bottle in the kitchen and one on my night stand, ready at any time for whatever. It's one of the few essential oils that can be applied full strength, and is especially effective on burns of any kind. I mix it with pure aloe gel for sunburn (only takes a few drops), and it really takes the burn away pronto.
BTW, I love your pic. I feel drawn to it somehow, your beautiful smile and kind, knowing eyes. It somehow makes me feel more peaceful, and quiets the buzzing in my head. Thanks for that, and the laugh. I needed it.
Victoria
