Barrage Laser and second opinion

I am 32 years old.

In my right eye, I developed 2-3 floaters (2 sort of clumped together and one like a thread) about 2 months ago. There have been no additional symptoms so far, such as flashes of light or an increase in the number of floaters. I got my eyes checked by an ophthalmologist today; my vision is overall fine (6/6).

The doctor said that I have lattice degeneration in both eyes (probably from birth) and suggested that, since I’ve developed some floaters, I should consider getting barrage laser treatment to prevent any future issues. He also mentioned that there are two schools of thought: one says not to do anything and just monitor the condition, as there is a very low chance that the existing lattice will cause further damage, and I should be fine without laser treatment. The other recommends that, since I’ve already developed a few floaters, it’s better to get the barrage laser treatment as a precaution.

Firstly, I am scared about whether it will be a painful process. I read online that I may feel a slight burning or pressure sensation, but some comments on Reddit said that the barrage laser was very painful for them, and one patient even fainted. Don’t they give any numbing anesthetics? I’m not sure if these are exaggerated stories or not, and I also read that some people developed new symptoms, like seeing flashes, after the treatment.

My father suggested I get a second opinion and weigh the options carefully to decide whether I really need the laser treatment right now.

Anyone else who face similar situation? Sorry for the long description, just trying to calm down my anxiety here.
