r/Dermatographia

Saturday night I started getting very itchy specifically around my bra, hands and scalp. I went to bed thinking it would go away (I get a lot of random rashes) but it had only continued and keeps getting worse. I finished an antibiotics about a week ago after a bad ear infection and I’ve read that this could trigger it? The rash appears about 10-15 minutes after any mild scratch or contact with skin. It lasts for hours and hours and then goes away but comes back somewhere else. Benadryl helps but hydrocortisone cream and Claritin are not touching it. I’m literally in so much pain and sobbing and my doctor can’t see me til Friday. I don’t know what to do and I’m wondering if i should go to the er? I know it’s not technically an emergency but I feel like I’m going to go insane and I don’t know how to cope.

Subject: 2-year-old’s skin condition flaring in humidity – Extremely itchy/painful bumps (Photos included)

Post Content:
I am looking for insight into my 2-year-old son’s skin. He’s had eczema since birth. After allergy prick tests and blood work, we changed his diet, which cleared up 98% of his body. However, he has these stubborn, very itchy, and seemingly painful bumps on his arms, hands, and legs that won't go away.

Key Observations:
• Triggers: This specific "bumpy" flare-up gets much worse in the summer when he is playing outside in the humidity.

• Locations: Mostly on his feet (as seen in the photos), but also his arms and hands. He still has some patches on his palms, elbows, and knees.
• The Struggle: Neither his pediatrician nor the dermatologist has been able to give us a definitive diagnosis for these specific bumps.

• Symptoms: It is incredibly itchy and he seems to be in pain from it every day.
Has anyone dealt with a condition that is triggered specifically by heat/humidity like this? We’ve ruled out a lot through his blood work and diet, but we are still searching for relief.

I am 36 F and i have been having skin issues on and off for years now
I have noticed lesions on the side of my neck in my scalp area that possibly look like creeping eruptions? And or scabies
I will also attach some pics from a similar rash on my back
If anyone has any insight please let me know 🙏🙏

My daughter first experienced this rash on Feb 21st. It has gone away and came back several times since then. It strangely only covers her face and neck, and the part of her stomach between where her pants hit her waist and below the bra line. We have not changed detergents, soaps or anything environmental that we can think of that would cause this. No known food allergies. She did start her menstrual cycle in Jan which we think could possibly be related but not sure. We saw the derm last week and they diagnosed Dermatographia which I believe is incorrect. The patches do fade and become very light but I can still see them very faintly and they look like dry patches when dormant. These pics are when it becomes inflamed and normally lasts a day or two. She has severe springtime allergies and takes Singulair along with liquid antihistamines daily. Derms suggestion was to give more antihistamines. Any ideas?

I came down with some type of viral/respiratory infection pretty suddenly about 10 days ago. It was really bad the first 3-4 days, I was coughing constantly, sneezing, extremely runny nose but also stuffed at the same time, and I could barely sleep because I’d be blowing my nose every 30 seconds. The second day of being sick, I started getting a little itchy on my arms and legs. If I would scratch the area, I would get small bumps that would get larger, super itchy like a bug bite, & hot. After a bit of not scratching or after applying anti-itch cream, it would look better. I would try not to scratch since it’d make it worse, but sometimes I would do it in my sleep and I’d wake up with bad scratch marks. The first few pictures are how it started out.

On day 9 (last night), my cough and congestion were a lot better but still there and it would get worse at night. My left arm and both thighs were no longer itchy and did not have the bumps. But out of nowhere, I started feeling a little itchy on my right forearm so I scratched it for just a few seconds and not super hard or anything. But then my entire forearm just starting welting up with bigger hive looking bumps than usual, and the entire area started burning and itching like crazy. I ran and grabbed an ice cube to rub on my arm to stop the burning. I tried to put anti itch cream but it started stinging so bad and I had to rinse it off. It had never gotten that bad, and I took a photo of how it looked after a few minutes (second to last photo). The redness and swollen bumps started going away after about 30 mins to an hour, and I held a cold compress on my arm. The very last photo is how my arm looked this morning, which was about 12 hours after it flared up. It’s almost like nothing happened besides some scratch marks.

Has this happened to anyone else? I’ve been debating going to urgent care, but as long as I don’t scratch it, I don’t get any hives. It also usually doesn’t appear on the exact scratch mark but just the general area. Any advice would help!
