Blood Tests and Dermatographism

by Maria
(Toronto, Canada)

There is so much comfort in reading this. I have had this skin condition for almost two years (May would make it 2 but I am praying it will be gone!!!) and I identify with the symptoms, the frustrations, the distress and the need to get better if not fine. Initially, I saw my GP who did blood work and all came back clear except for an increase in my WBC (lymphocytes & eosinophiles) which apparently means that your body is fighting something. My GP referred me to a dermatologist who looked at my skin, scraped it a little and in less than 5 minutes told me that I was suffering from physical dermatographism! I was like huh, physy-what?? He just asked me to take Claritin and buy a certain cream. I wasn't convinced.

I had more blood work done, got the same results, and another referral to a different dermatologist. This one said my skin looked very clear (which can be misleading) and said it might be an issue with my nerves! I refused to buy it! I did more blood work to rule out more stuff and same results - showing active WBC.

So I decided to see a naturalpathic doctor who naturally asked for blood work to be done (by this time I am desperate and tired). Same results, all clear except for the active WBC!

So like some of you, I have been googling up things regularly to try and find out what is causing this. I even considered the nerves suggestion but I have just dismissed it. The itch is usually very intense/severe and worse if there are any markings like t-shirt markings, chair markings, etc. I feel it the most on my back and sides. But guess what guys? I have also decided that this ain't gonna rule my life :)

Personally, my back and sides become extremely itchy (especially at night) and I get big red welts all over. From what I know, it seems as though this condition is caused from the overproduction of histamine. Taking an antihistamine, like Benadryl, takes away all my symptoms.

Such a relief to find others in the same condition
by: Brian Penfold

Hi All,

I have had two lots of spinal surgery since December 2008. Prior to then I had no skin problems or allegies. About six months after the first surgey I developed all over eczema and a bunch of other itchy sites. I was eventually given steriods and it all but dissapeared except for my ankles. About six months ago I developed marked dermographism and rhinitus. It seemed to come from nowhere. To cut a long story short, I have had more surgery to replace the titanium artificial disc C5/C6, and had loads of blood work done. The results have all come back negative with the exception of a high eosinophil count, and I cannot shake the marked dermographism or rhinitus. I waiting on IgE and RAST test results at the moment. I do get the odd stomach pain (liver/spleen) when the dermograhism is at it worse (i.e. really reactive); although some days I hardly know it is there at all.

I have been worried to death that there is something more sinister going on - but all the tests do appear to show that is not the case.

The doctor is looking at another dose of steriods soon to see if my autoimmune system can be reset.

Has anyone got any tales of a cure?

B12 Deficiency
by: Anonymous

You should get your B12 checked. I have dermatographism as well and my dermatologist said that it could be related to a vitamin B12 deficiency and sure enough mine was very low. If left untreated, it can cause permanent damage to the nervous system. My dermatographism has not improved but my other symptoms sure have. I have had this condition since forever and I don't know what it's like not to have it, so I guess in one way I'm lucky. Ignorance is bliss!!

Dermographism is Not Ruling My Life Either
by: Anonymous

I was also diagnosed with dermographism, my GP prescribed two meds and I am free of the symptoms since. I took Ebastine 10mg (in the morning) and Hydroxizine 25mg at night. After 6 months it is gone!!! Just ask your GP for advise on that. Good luck!
