PLEASE HELP left side sharp pain in lateral chest area

So it's a sudden random sharp stabbing pain in my left side and it hurts even more when I take a deep breath only hurting when I'm getting the sharp pains. And I don't really know what's going on or if anyone else has experience before. If so please let me know. It's been happening for awhile now. And with my dad having surgery it's kinda hard to afford a doctors appointment.
