Recently I've have a vet bad chest cough.. However within the last several days I've also developed a sharp pain on my right side. It's about 4 inchs under my armpit, under my rib cage.. It's also very tender to the touch.. I've also began coughing up blood, this began today.. Not sure what to do... :/

See a doctor. We can't diagnose this and if you're coughing up blood, this is not something you should wait on.
