I was recently prescribed a Nebuliser by Harefield Hospital. I tried it 3 times and had a bad reaction. 125 pulse rate, oxygen decreasing and swollen feet. Felt terrible. I did question this latest treatment because as well as Severe COPD I also suffer with Severe PH. I stopped using it and checked with the COPD Nurse who agreed with me. I guess for some people it is successful. Anybody else had this problem?
