Re: Lower left quadrant lump and pain?
If I were you I would stop searching the internet and go and see your family physician. Tell him or her that you are feeling a lump that was not there before and have them check it out. You need a practiced hand to take a look at what it is that you are feeling. Make an appointment and in the meantime, see if the lump is still there when you lie down. There are muscles in that area also that harden when you are standing.
Put your mind at ease and go and see someone who can tell you for sure.
Take care and best regards.
