Hi, I recently got rid of and old oil burner in my basement. I cleaned the ash off the floor, but it seems to be lingering for days in the air. I have been working out in my basement while I train for a half marathon. Recently after running I have noticed a very dull, slight pain in my lungs................Is this the ash trapped in my lungs and will it go away? It doesn't hurt that badly, but the half marathon is this Sunday. I appreciate any help and guidance.
Thanks,
John
