Lindsay Lohan was complaining about stomach pains this past Wednesday, when she went to the doctor and found out she was suffering from appendicitis. Doctors adviced her of needing her appendix out and that's exactly what she did. Honestly I don't know if a normal person (one not rich with lots of money or a celebrity) would be able to have this done so quickly but she did.
Currently Lindsay is recovering in the hospital. One good thing about this is when she felt ill she immediately went to the doctor, most people would just dismiss it as a common cold or something. Keep in mind that things can happen to anyone, including yourself, if you feel ill get it checked out.
