Good morning,
I'm sorry to hear about your diagnosis. However, I can tell you that you are not alone. PLC is among the rarer skin conditions, but there are several of us who, for lack of a better term, suffer from this condition.
I want to first start by saying that I am not a medical professional, and in no way should my advice substitute medical advice. This is all coming from a place of opinion and my own personal experience.
To answer your question, if the Tetralysal is not helping, I recommend asking your doctor about Topicort (Desoximeasone Cream USP 0.25%)
This is the only, and I emphasize ONLY cream that has worked for me. I've tried several other prescription ointments that should have done the trick, but the spots persisted. The Topicort cream helped me to heal very quickly. It is also a steroid cream.
One of the most important things you can do is be vigilant when it comes to your skin. Try to catch these little spots when they first start. I'm sure your dermatologist already gave you information about lifestyle but a few tips I'd also recommend:
-NO shower “puffs” or sponges or wash clothes or anything that exfoliates the skin. Throw them away, forget they ever existed. I was irritating my skin so badly and didn’t even realize it until my Derm scolded me for using those. She also recommended I switch to dove bar soap. I’m currently using Olay sensitive, but I’m considering switching back to Dove.
-Take only luke-warm to cool showers, and try not to spend a lot of time in the shower. My skin practically tells me when I've been under the water for too long. My arms will start to feel "tight"
-Switch your shampoo and conditioner if need be. Some products have a lot of chemicals and can irritate our skin.
-Switch to a fragrance free laundry detergent for sensitive skin. And NO more dryer sheets or fabric softener if you use these products. That makes a HUGE different for me.
-This one is going to sound silly but…I noticed that if I wear underwear with any type of “lace”, it will irritate my skin around my hips and I will have a flare up. Sometimes after washing and drying lacey materials over and over again, the material itself starts to become abrasive.
-A lot of people rave about coconut oil. I've only recently started using it on my face at night to help remove makeup. I'm actually going to post a topic because I need some advice myself regarding face concerns. I wish I had more info on that.
Some people have seen good results with a daily anti-biotic. I have to be honest, my Derm prescribed antibiotics for me to take daily, and I have not taken them. I personally have adverse reactions to some antibiotics or their side effects, so I’m just not comfortable with taking them regularly. But that is not to discredit antibiotic treatment. It works wonders for some people.
I’ve studied a bit lately about photo-therapy lately. It seems as though some folks with PLC/PLEVA/Mucha-Habermann’s have seen good results from UVB therapy. This is usually done at the dermatologist’s office. No dermatologist will recommend laying in a tanning bed, or standing in a tanning booth at a tanning salon, BUT some folks claim to have seen excellent results from doing so. If that is something you are considering, I recommend reading a LOT about it first and discussing the pro’s and con’s with your doctor. Not all UV beds are alike. And that that type of exposure is strongly linked to Melanoma (skin cancer) and we do not want that!
And finally, I don’t know how much weight this theory holds, but I’ve noticed (with myself) a link between flare-ups and being “sick” with any type of cold or virus. Every time I have a cold, I have a flare up. I even had a sinus infection a few weeks ago and I had papules appear on my chest and neck, after being clear almost all summer.
Everyone experiences their symptoms differently, but I hope some of this can help you cope better with this condition.
If I think of any more tips I will post again for you. Good luck, and welcome aboard. Hopefully one day there will be a solid fix for this. In the meantime, these forums are a great place to share advice and help one another. Have a good day!
