### input:
On Oct 1, last year I hospitalized with a severe all over body rash which was treat with rednisone and antihistamine.  During my hospitalization I went into respiratory arrest as my throat closed and was kep in intensive care fr a week.  Since then I continue to get rashes daily all over my body and feel fatigued all the time.  The rashes are brought on by food (the list of food changes all the time and I seem to become tolerant of food if I persist eating it), also going outside in the countryside with lots of vegitation brings on a rash.  Further, exposre to cold air or change in temperatur/wind, brings on the rash.  Also physical exertion such as fast walking/exercise/gardening.  The type of rash varies and where it apepars on my body.  It is always itchy.  I also experience heart pounding, shortness of breath, general unwell felling like flu symptoms when the rash appears.  Nobody seems to be able to diagnose the problem.  I have been on low dose steroids for long peridos, but it does not sold the problem.  Can you help?

Hello, Thanks for the query to Chat Doctor. Forum. All the symptoms, which you mentioned in your query correlates with a lung disorder as note down, Airway hyperresponsiveness that is secondary to inflammatory airways' disease that results in recurrent or chronic episodes of wheeze, shortness of breath (S O B), chest tightness &/or cough particularly at night or early in the morning. Symptoms are usually associated with airflow obstruction, obstruction is usually reversible either spontaneously or with treatment. This is actually allergic asthmatic bronchitis. Consult a physician and get expert opinion. Hope I have answered your question. If further any question I will help. Good luck.
