Rash from the sun

[cecilsusie]

I was recently in a rehab that was in a county jail.  I was there for 6 months, and during this entire stay from Nov. 7 thru May 5, 2008 I did not see outside nor did I get to go outside.  Now that I've been home and working outside I get this terrible rash on my arms, chest and back of my neck from the sun.  I didn't over do it by staying out in the sun to long .  I'm wondering if this is caused from no sun light for 6 months straight?

Hi,
Physical allergies are allergic reactions to cold, sunlight, heat, or minor injury.The immune system usually responds only to certain kinds of chemicals, namely proteins. However, non-proteins can trigger the same sort of response, probably by altering a protein to make it look like a target. Physical allergy refers to reactions in which a protein is not the initial inciting agent.
Sunlight, even without drugs, causes immediate urticaria in some people. This may be a symptom of porphyria--a genetic metabolic defect.
Shade(USE A HAT) and sunscreens are necessary when you are out in the sun.
The reaction can usually be controlled with OTC antihistamines.
Itching can be controlled with cold packs or commercial topical agents that contain menthol, camphor, eucalyptus oil, aloe.

Hi,

What you describe seems like sweat dermatitis or heat rash.

You should try to keep the area dry and clean. Try some powder to absorb the sweat.

Use a medicated sun screen whenever you are outdoors; try to avoid direct sun exposure, use calamine lotion at the sites to help soothe the lesions.

If the symptoms are still persistent, consult your dermatologist and get a proper clinical evaluation done.

Let us know if you have any doubts and keep us posted on how you are doing.

Good luck.
