My ear lobe is red swollen and my jaw is starting to hurt at the hinge.. my ear hasnt been pierced since i was like 10 or younger, why is this happening now?

Probably need med: The symptoms you describes are worrisome for an infection developing. You should see a physician or do a virtual consult to ascertain the problem. Happy healing.

See a doctor: Either you reinjured your ear lobe by forcing earring, or you used earring made from material that you might be allergic to ,so see a doctor for proper evaluation and treatment. Meanwhile take the earring out apply topical antibiotic and take Benadryl (diphenhydramine) by mouth. Again see a doctor.
