You seem to have a very good grasp of the complexity of your situation. I would doubt that there is any hyaluronic acid left after 6 years and that the problems you are having are more from cysts under the skin. Excision of these, while leaving a small scar, is usually less conspicuous than the bumps themselves at conversational distance.
It is also possible that what you had injected was actually not HA. Back then people were using some more permanent fillers like Artecol (Artefill) and liquid silicone. These have been associated with granuloma formations years after treatment that are very difficult to eradicate.
I would recommend getting your medical records and confirming what you had injected because a good doctor will specifically record that in the chart. Nowadays, we even place a sticker from the syringe directly in the patients chart.
