Pain on upper left near belly button

[Justtheoneplease]

I know I probably need to call or see a doctor but with everything as it is I don't know what to do.
I'm late 50's. Female post menopause. Had my gallbladder removed about 10 years ago.
For the last few weeks have had a weird pain/discomfort just above my belly button on the upper left side. My tummy is very bloated.
I've googled and frightened the life out of myself.

I don't know what it is. Feels tender like inflamed, no lump as far as I can tell.
Petrified it might be cancer

Bump...

Please make an appointment to see your gp tomorrow, they will be able to put your mind at rest or set the ball rolling. I had to see gp this week, mastitis got a nasty infection. It is annoying that our female bits still continue to play up post menopause. I am now on disgusting tasting high dose antibiotics to clear up my problem.

I naively thought that female problems were behind me, it seems not. Grrr....
