Your chest tightness may be related to work if it occurs when you are at work (or soon after leaving work) and improves when you are away from work (e.g. weekends or when on leave). At the NIOH we can assist in the diagnosis and management of your work related respiratory problem. We can do allergy tests (skin prick test and other specialized tests) specific to the materials you are exposed to at work if appropriate. We can also test for reactions to non-specific, common substances (e.g. grass, house dust, trees, cat etc.) in order to determine whether this may contribute to your work-related chest tightness.
