What Causes Exertion Induced Rashes On Abdomen And Legs?
May be exertion induced rash
I have gone through the question and understand your concerns.
It seems that you have exertion induced rash. Exertion can cause release of histamine from mast cells. It is possible that the long shifts that you are doing might be causing damage to the muscles.
The muscle damage causes the release of histamine which leads to rash. Some of the symptoms of this are:
Rarely difficulty in breathing
You can manage this with antihistamines and with regular massage. The regular massage will help you prevent injury to the muscles. If you plan to take antihistamines, please see a doctor to get anti-histamines.
If you start getting severe symptoms, you need to see a doctor to control the difficulty in breathing or the rash continues for more than a week.
I hope this answered your query. Please post a follow up if you have further questions.
