There was a bleach leak from the apt above me into my place through ceiling. i now have a dry cough and painful throat. are there long term side affec?

Depends: It depends on how long you were exposed, the level of exposure, and any contributing or systemic issues you may/may not have already. I see you smoke cigarettes, that doesn't help the overall situation. Take a break for a week, it will help. Make sure your apartment has been cleaned, professionally. Keep windows open as much as possible. That is a chemical spill.
