Clinical narrative: Started the evening of 11/18 ? my left back thigh and inner right thigh were itchy.  I could feel a bunch of small bumps.  At 1:30am I woke up with intense itchiness.  I took a picture to see the bumps.  They were smallish welts/hives that looked similar to the reaction I have to mosquito bites.  I put on over the counter hydrocortisone, which helped calm the itching.  Then, I started to notice that I was getting itchy other places ? my back, side, stomach.  I continued to put hydrocortisone to ease the itchiness.  By 8am on Friday the 19th, I had red patches in various places ? legs, stomach, back, upper arms.  I took a Claritin and continued to use hydrocortisone to ease the itching throughout the day.   The hives would come and go throughout the day. 11/20 ? woke up with red itchy patches in armpit and surrounding area, back, thighs/groin/leg crease area.  I took Benadryl and used hydrocortisone throughout the day.  The areas continued to stay red, would itch and hives/welts would come and go.  I went to Urgent Care that evening.  While I mentioned to the medical assistant that I think it could have been caused by my booster, I don?t think I relayed that information to the NP who treated me.  I received a shot of mtheylprednisolone 125mg and famotidine 40mg at urgent care and a prescription for hydroxyzine 25mg.  Shortly after the shot in the butt, my lower back burst into hives.  The NP told me if it didn?t get better soon that I need to go to the ER.  The hives eventually went away within the hour.  Interestingly, when I took the bandaid off from shot, my skin was bright red where the bandaid adhered to my body.  No itching or hives, just bright red.  I then started to notice that my skin would turn red with the smallest ?trauma? ? scratching, holding a bag on my arm, seams from clothes.  Sometimes it would cause hives to appear and itch.   11/21 ? I woke up with all of the red patches gone, no itching, no hives.  The red patches that I had in my leg crease and lower back had turned brown (not my normal skin color).  By 11/22, the brown color had disappeared.  I continued to take the hydroxyzine. 11/22 ? most of the day was free of any redness, hives and itching.  By the evening, I had started to notice red areas on my arm, back, and stomach.  But I don?t recall it being too itchy. 11/23 ? Woke up with a red itching and hurting patch in my armpit and surrounding area.  I took Benadryl (not hydroxyzine because I had to work and feared the drowsiness) and used hydrocortisone.  That evening, I used my son?s Aveeno Baby eczema balm on my armpits to try and prevent another flare. 11/24 ? woke up with large red patches/flares on my thighs and sides, hips, back.  I used Eucrin baby eczema cream to help and continued with Benadryl. I would take Benadryl during the day and hydroxyxzine in the evening/bed.   11/25 ? random and various areas continued to flare and itched.  Continued the same: eczema creams, Benadryl and hydrocortisone.   11/26 ? Now, I?m having small red bumps all over my stomach and thighs.  Sort of looked like measles.   The measles like red bumps persisted.  They were bothersome and lightly itchy.  Still had random areas flare and itch.  11/27 ? I started to notice red marks on my face, but they didn?t itch or hive and would disappear relatively quickly.  For the most part, the flares/patches/hives were concentrated to legs, upper arms, stomach, back and backs of legs.  Neck, face, lower arms and lower legs were not affected.  But now I?m starting to notice that red marks appear on lower arms and face but quickly go away.  11/29 ? the bumps appeared again on the back of my thighs ? as it did when it first started.  Also present on back. 11/30 ? had some ?trauma? to arm from rubbing against purse.  Red marks and hives appeared.   12/1 ? woke up with hives now appearing on top of thighs, side of back/hips, and leg crease area again.  And were itchy again.  Red patches appeared on upper arm/armpit area.  Until this point, my feet hadn?t really been affected.  This evening, I had intense itching on my left foot.  It turned red, but no hives.  The redness and itchiness eventually went away within 30-40 mins.  12/2 ? went to family nurse practitioner about it.  And to get a referral to the dermatologist and she also recommended a referral to an allergist.  She prescribed cetirizine 10mg daily for the next three weeks.   12/3 ? most of the day was mild.  Very little redness, itching and hives.  However, as I approached the 24 hour mark for the cetirizine, I?m noticing various areas starting to itch. I have an appointment with a NP in dermatology on Dec 13.
