very odd - one breast has suddenly started producing milk ........

[blushingm]

just out of the blue

Has anyone any ideas why this might happen?

It needs checking out by a doc I would say.

It could be related to medication. Can't remember off the top of my head which ones, but I know some meds can cause this to happen.

i do take regular medication

priadel, fluoxetine and liothyronine - would any of these cause it?

is it something bad if it's not caused by the meds?

I'd check out the side effects of your meds first and then see the doc as any odd discharges should be checked out.

I'm sure it could be connected to your thyroid though.
