What is this? Discoloured bump on lips. Had lip fillers 8 months ago (Photo)

It's understandable to be concerned about changes in your lips, especially after having lip fillers. Based on your description, it seems that the discolored bump is not causing pain, but any new or persistent changes should be evaluated by a healthcare professional to ensure proper diagnosis and treatment.

There are several possible causes for a discolored bump on the lips after filler injections:

Post-inflammatory Hyperpigmentation: This can occur after trauma to the skin, such as from an injection. It usually fades over time but can take several months.

Hematoma: A bruise or collection of blood under the skin might cause discoloration and a lump, which typically resolves on its own.

Granuloma Formation: This is a rare reaction to filler material where a small lump forms. It can be treated if necessary.

Vascular Compromise: Although you mentioned a vascular occlusion, this is typically painful and would have likely presented immediately after the procedure. However, if you have any concerns about blood flow, it's crucial to seek immediate medical attention.

Other Skin Conditions: Such as benign lesions or even, though less likely, something more serious like melanoma.

Since the treatments suggested by your injector have not improved the condition, it would be wise to consult with a dermatologist or a healthcare provider experienced in cosmetic procedures. They can assess the area and may recommend further investigations or alternative treatments. Always better to err on the side of caution with any new or persistent skin changes.
