Hello, I am 45 asthmatic and currently having some tightness in my chest and a short breath sensation when speaking and walking even. I try to run but cannot get too far before my legs, chest and whole body basically aches to the point of hurting if I try to push myself to jog. I have had asthma for years taken treatments for it when it got bad during the spring and so fourth, but recently I have had this underlying chest tightness and sensation of shortness of breath and some dizziness when yelling or raising my voice. It is somewhat difficult to take deep breaths as well. I am unemployed at moment, but I did work in a facility that had used motoroil as coolant and breathed it in for about 2months before I had to quit due to very bad chest and lung congestion and ear aches. After I quit the symptoms subsided, but I still have this underlying feeling that my bronchi tubes are inflamed or become in flamed a lot more often then they used to. I currently do not have health insurance and I hope this is not a heart problem. Can you offer some preventative action for me to take. Thank You J.G.
