Plenty. I presume this is stress related so you need to resolve the stress either by talking with your supervisor to change circumstances if this is possible or seeing a counselor to help you learn stress coping techniques. If you cannot resolve the problem with these you may need to seek a new job. If this is not stress related see your physician to look for more serious causes www.Medac4u.Com.
Inhalers. Occupational asthma can be treated by avoidance measures. If that is not possible then medicines such as albuterol inhalers would be the next step. If albuterol is used frequently then inhaled steroids would be considered.
