I am fiifty four years and suffers almost on a weekly basis from coughing, weezing and runny nose. I have been told by my doctor that i am asthmatic. I have been taking all kinds of antihistamine including, aeroflux, histal, benedryl,aerius but as soon as i finish taking them the symtoms comes right back. Sometimes my chest seem as if it is expanding like a balloon ready to blow up and a tightness/pain which can be felt right through to the center of my back. At times i cannot even lie down because of this tightness. Please help me I am now worried that tis is beginning to affect my heart. Thanks much Antonette
