<human>: I Have Red Dots That Appear And Disapear Randomly, They Seem To Be Connected With Changes In Heat And Cold . It Depends On How Hot Or Cold It Is, Sometimes Ill Get As Little As Ten To As Most As Uncountable. They Vary In Size And Itch Sometimes. Doesnt Matter On The Temp They Always Produce Heat Even If Its Really Hot Out. Once I Went To The Doctor For It They Said They Didnt Know, But My Skin Was Extremely Sensative And That They Didnt Know What It Was.
<bot>: Hi Dear, i can imagine the situation when a doctor say they didn't know what it was :)But anyway I have gathered from your question is that you are definitely suffering from Urticaria it will need a formal discussion to reach to a final type of it but I think cold or cholinergic urticaria must be differentiated at this point. You have to do some labs asked like a FBC, LFTS and a Urine R/E. But the good news is you can use certain anti histamines in the meanwhile like Tablet Fexofenadine 180 mg daily in the day notable Zyrtec 10 mg in the night for at least 2-4 weeks before you come up with your results.Don't get so hopeless just try to discuss it with a dermatologist that could it be certain type of urticaria and then I am sure he'll manage from there, all the best
