i'm pretty better now, the doctor did me a radiography and we saw what you are talking about (the spots in the lung)

Glad to hear you are doing better.

i had quit smoking a week ago before that happened, i did not tell that to the doctor until now, he said me that's not good for lungs of course and maybe have caused that spots

Your doctor is right, smoking can contribute to these weak spots.  The reason is that the lungs are also dependent on the structural proteins collagen and elastin for strength and elasticity.  These proteins depend not only on the presence of silica, but also vitamin C.  The adrenals get priority of vitamin C over the entire rest of the body followed by the retina, then the brain, etc.  The lower on the priority list a tissue it is the more likely it is to become weakened as the adrenals are taxed since the adrenals use up even more of the body's available vitamin C.  Smoking puts a lot of stress on the adrenals significantly dropping levels of vitamin C available to many of the tissues in the body.  This causes these tissues to weaken from the loss of collagen and elastin.
