Hi, I'm a 24 year old male. Roughly 2 weeks ago i carried my push mower up my basement stairs, not thinking at all before doing it about how heavy it is. Within a day or two after i developed a sharp pain in my ribs and a small lump above my left nipple. The nipples hruts when i touch it, almost like it's sore. I thought it would go away but Sometimes the rib pain was unbearable and i was growing concerned about the nipple lump.
I went to urgent care in my town, they took some x-rays and i went for an ultrasound. Both showed nothing. The doctor there gave me a prescription for 800mg ibpreoufen. I'm getting more and more worried about this lump. I'm starting to worry about cancer. Should i be worried about cancer if the ultrasound showed nothing? Could the rib pain and the nipple lump be connected? Any insight would be appreciated.
