Ever since I moved to Melbourne, Australia for university I've been experiencing abnormal itchiness typically starting from the chest to my back. This makes my pre-existing psoriasis a little harder to bear as I sometimes scratch affected spots thus making it a little harder to heal up.
I used to live in a very humid, equatorial climate and thought this was a reaction to the relatively lower humidity down here. I started using moisturising lotion as recommended by my GP at least once every other day but it didn't help for 6 months so I stopped as I deemed it a futile effort and a waste of very limited funds.
This problem usually arises when my body gets warm internally. Examples are when I drink alcohol, eat/drink hot soup, work out, cleaning and even simply walk short distances.
The only time something seemed to work albeit for a short time was for a week after I spent a couple hours in a sauna. I also realised the problem usually disappears the moment I start sweating profusely.
Is this a known condition and can it be managed or treated?
I am not a doctor, so you might want to see one, but here are a few thoughts.
1 Where you live now is warmer and less humid, so dryness issues arise in my mind. Your skin may be too dry.
2 Alternatively when you eat something hot the blood goes to those areas, thus you feel hot.
3 The other thing could be about circulation, or should I say lack there of. But I am included to think it is #2, above. or a combination of 2 and 3 where you might have some circulation blockage issues and the exercise helps, in addition when you start sweating the problem goes away.
See what happens over another week or so and if nothing gets better you probably could go see a doctor and see what they say. If it is circulation related you should probably address that, and doing exercise is a great way to get the blood moving.
These symptoms can be due to cholinergic urticaria. It is a form of chronic hives that is caused by an increase in body temperature but can be idiopathic also. Take some antihistaminic like Benadryl or Claritin and apply some calamine lotion on the hives. If the symptoms persist then please get it examined from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided.
