Lisinopril and alergic

I have been on Lisinopril/HCTZ 20mg for about a month. I have severe fatigue, trouble sleeping, cough, sneeze and have a hideous rash on both arms that itches and is spreading to my back and shoulders. Saw my MD yesterday and he thinks I might be alergic to HCTZ (tried to tell him I was on that for 6 years --no rash -- no side effects) he has now prescribed Linisopril with nothing added. If this has not cleared in one week I'm going off the Lisinopril. I'm wondering what this drug is dooing to my vital organs. Do you think the reaction is confined to just the outside of the body?? I don't.

I am 42 and started BP treatment almost three months ago, I thought that I was just having side effects from the Flue shot, but now the Dr. feels that it is side effects from the Lisiniprol 10mg. My joints ache from head to toe, Cough, fever, sore throat and infamous cough. Oh what a wonderful thing! I was so excited as the blood pressure went down and was at a normal level now I am afraid to start something new. yes we decided to go off the medecine "emediately" continue 5 days of BP check and go from there., Go figure find something that helps, and BAM Alergic.. good luck to all those out there hesitant to try something new,. then to have the side effects.. I pray that the side effects will go away now that I stopped taking it, especially the joint pains and muscle cramps.. I am not overweight and pretty active but this has made it hard to move especially stairs.. Good luck
