Hi joavila and welcome.
First of all I am sorry that you are going through so much worry right now in regards to your health. Know that you are not alone, and that we have had many, many posts similar to yours. A lot of members here struggle with health anxiety, myself included.
Our solemn pledge and motto...
NO Googling symptoms! This inevitably leads to more anxiety...and needlessly so. Those search engines are designed to route you to every possible match for what you input as a symptom...so basically you are going to get a whole bunch of scary things popping up that aren't even close to what you are dealing with!
Trust your doctor. Boils, absecesses and cysts happen in completely healthy people. It may take awhile to completely heal, and yes you may have a swollen gland(s) because this is the body's natural way of figthting the infection.
Keep taking any medication that you need...making sure to finish the course completely. Also, get plenty of rest and good nutrition to keep your body strong while it is healing.
If you feel any more panic, check out our Anxiety/Panic Resources (main page 2nd post) for some great self-help techniques such as breathing and relaxation exercises...they really help.:)
Keep posting with us as well. It is really comforting to talk with others who undersand what you are going through!
Talk to you soon,
S.C.
