Head pressure and rashes

[xxDAYVOxx]

I have had head pressure for about 3 years it go's on all day every day. My ears pop and I get ringing noise in them but it is not all the time once in a while. My mucus in my noise is pure white and thick all the time.  My heart started fluttering about three months ago and I started to get these rashes all over my body but only when you put pressure on the skin, when it get irritated it gets large welts and very red. I'm tired all the time don't know why?
  I went to the doctors for about the whole the time this was going on.I've seen the ENT and Allergist, the ENT did a rhinoplasty and that did not work, they did cat scans,MRI's,Blood work,Xrays,Blood work for allergies and everything comes back negative. I just got done with a holter monitor but the results have not come in yet.
  But when I was younger I played a lot of sports in high school and I was very active. But when I got this welding job all these problems started to happen one by one, the first year  was fine but it seemed like the company I worked for did not have the interest anymore in the employees health and they did not maintenance the ventilation so know it catches on fire and the smoke is yellow like mustered. Don't know if this is the cause of my problems but I would like to know what I could tall my doctor so I can get diagnosed.

I agree with Remar, it appears that the environment at were you are employed is playing a major role in your problems I would see the doctor and explain your work environment to them, he should do a complete check up on your lungs which includes some scans to rule out any thing serious. Having chemical allergies can contribute as well, and I would be willing to bet you are allergic to the stuff at your job.

It sounds like your job may very well be what's causing your problems. Have you had your lungs checked? You need to have that done. I would'nt be surprised if there was inflammation. Your probably allergic to the smoke at your work. Tell your Dr exactly what's going on at your work place. This will help them diagnose you.  Remar
