Latest update from July visit

I had to get some paperwork completed for work so I got to see my pulmonary specialist again. It was actually a necessary trip since I have been having more problems breathing and have been coughing up stuff over the last few weeks.
The stuff that I am coughing up is not coming from my lungs. My doctor said that I sound clear. I'll have to see an ENT but I can do that here.
I had/have appointments in August with the new cardiologist, rheumatologist, and neurologist. When I got home I found a letter saying my cardiology appointment had been rescheduled. So now I have to work on rescheduling everything since I can't afford to stay down there three days.
My pain level has been off the chart today. I was so close to breaking down and crying several times at work today. I know I am having to use the heavy painkillers more often than I want because they no longer make me goofy or hyper.
I need something to change and change soon. I really don't know how much longer I can continue like this.
