For the last couple weeks I've been experiencing discomfort in my left side, just under the ribs. The area is not visibly swollen, but it is slightly tender.
Over the past few days I've felt occasional twinges of pain when I breathe too deeply. The pain is mostly centered in my left side, around the original source of discomfort, but it's also in my diaphragm.
Two days ago I developed cramps in my lower back, which is normal. What isn't normal is that they're still here.
As of today, my whole chest feels tight.

Does anyone have any help or advice about this? Money is too tight for a doctor to be feasible, and things are so stressful at my house that I haven't told my parents. The pain is slight, and it doesn't affect my activities or sleep, but I'm worried by its growth and spread.
