Had a biopsy on left breast lump last year, got diagnosed with fibroadenoma, can it cause pain? an little swelling

Yes: They can cause pain. Sometimes can grow.

Sometimes yes: If a core biopsy made the diagnosis, i would repeat an ultrasound, to see if the fibroadenoma grew. Even though benign, fibroadenomas can grow. If the growth is substantial, i would recommend removal, to r/o a phyllodes tumor. This is a tumor w malignant potential that can be difficult to distinguish from a fibroadenoma on core biopsy.

Fibrous demons: Those lumps are sometimes tender to touch they are usually benign. Excessive caffeine intake can make them more prone to happen.

Possible: Fibroadenoma of breast most of the time painless or will give minimum discomfort, if you have only biopsy and tumor is not removed completely may cause pain due to tissue reaction & scar tissue then get it removed , if removed go back to your surgeon for evaluation possible tests.

It may: Your breast fibroadenoma maybe enlarging. However, there may be other causes for your breast pain and swelling. I would suggest that you have a medical evaluation.

Yes,: a fibroadenoma can enlarge and/or cause pain. But at this point you don't know if the fibroadenoma is causing your new symptoms, so you need to see your doc for an evaluation.
