Agh, don't use any kind of anesthetics (basically, -caine containing) medications on sunburn as they can be very sensitizing and make you allergic to them later on. (It really sucks that drug companies market anesthetics for sunburn because you're worse off using them then not using them at all...)
Here's what I would recommend (as a pharmacy student, so there's some merit in what I'm going to say):
First of all, you should see your doctor if you're experiencing any of the following:
Severe pain
Severe blistering
Headache
Confusion
Nausea or vomiting
Fainting
Really bad causes of sunburn can actually cause dehydration and get your electrolytes out of whack, so I definetely advise keeping hydrated with fluids while you're experiencing this.
Basically, for self-care:
- Cool compresses, where you take a small towel and soak it with equal parts of milk and water, then place it on your burn may suffice. You may also use cold compresses with Burrows solution.
- Cool (not ice cold) baths may help.
- Avoid bath salts, oils, and perfumes because these may produce sensitivity reactions. Avoid scrubbing the skin or shaving the skin. Use soft towels to gently dry yourself after bathing, and definetely don't rub the sun burnt skin.
- Use a light, fragrance-free skin moisturizer to get some more moisture into your skin.
- Pain relief medications, such as ibuprofen or acetaminophen will help to control the pain you're no doubt experiencing. If you decide to go with ibuprofen (Advil) make sure to take it with food since it is hard on your stomach and can increase your risk of getting ulcers. Acetaminophen (Tylenol) is much milder in that you don't have to take it with food, and that's what I'd recommended. It's not an anti-inflammatory like advil, but you don't need an anti-inflammatory in this instance, only pain relief, and Tylenol will do just that for you.
- Aloe vera gel does provide a cooling effect on the affected skin and helps moisturize it, but it's effect is pretty short lived (usually up to 30 minutes), so you have to keep reapplying it and it does get kind of messy.
You also mentioned that you're experiencing a lot of itchiness lately. It could be due to the natural process of shedding the burnt skin, or it could be due to the fact that you've been applying this solarcaine and have developed an allergic reaction to it. For the relief of itchiness, I'd recommend diphenhydramine (Benadryl) - it's an anti-histamine so it'll help to reduce the itchiness. The downside with it (or it could be seen as a benefit depending on how you look at it) is that it causes drowsiness. What I would do is take a dose of it at bedtime and that will help you to sleep and not be so itchy. During the day you could try taking some (maybe less than the usual dose) and see how it affects you. Some people are more affected by the drowsiness than others, it's all individual.
SO, in summary, here's my recommendation:
- Acetaminophen (Tylenol) [for ][/for] - follow the directions on the bottle. It's usually 1-2 tablets every 3-4 hours as needed.
- Diphenhydramine (Benadryl) [for ][/for] - 25-50 mg three to four times daily (max dosage = 300mg per day). It'd start off taking a dose at night (50mg), and then trying a dose of 25 mg in the day and see how it affects you. Use it as needed for the itchiness.
If the itching becomes worse and doesn't go away after using the Benadryl go to your doctor.
