My doctor prescribed Asmol CFCS Inhaler as I suffered from Acute Bronchitis. I am 75 yrs old and occasionally suffer from leg cramps. However yesterday I suffered a lot of cramps in my arms, hands and fingers. could this have something to do with the Inhaler. I have used it for 2 days, without much effect. Also for how long is Acute Bronchitis contagious, I have no fever anymore, just a lot of coughing but no secondary infection. Thank you very much for your time and assistance. Konrad
