I have swelling on left side of the bottom of rib cage when I touch it not the same as right side no major pain but discomfort and sometimes feel slig?

Trauma? Shingles. Dear YKarim, have you hit the area? if not, when reading this, I got concerned about Shingles (Herpes zoster) in which case, early antivirals will help. Monitor if you develop redness or bumps in the skin. Costochondritis is another though. A virtual or personal consult might help to clarify the reason. Good luck.
