Chest pain after inhaling hot ash from tobacco pipe. my question is can i hurt myself from this? any help in this regard is greatly appreciated

Yes: Hot ash would be very damaging to the frail mucosa of the respiratory tract causing burn injury, not to mention the long-term carcinogenic potential (worsened because of combination of physical trauma with carcinogens in the smoke). Could also act as an irritant producing bronchoconstriction/wheezing/shortness of breath in certain people. Hope this helps.
