Internally scarred glans. Uncomfortable,

Hello, doctor I'm 22, and had systemic fungal infection, and also had severe fungal infection on the glans, so I used povidone-iodine 10% on the glans, thinking it might kill the fungus, but after some hours of applying it, my penis became totally numb, and gained sensitivity back over months, it's been more than a year to that incident, but still after the incident, it feels like there is something inside the glans, which is stopping the full sensation from coming back, I think, I might've scared the inside the glans of the penis, which is giving me such a sensation, so, is there a way to get rid of the internal scar, as due to the scar, while having sex my right side(scarred), of the glans, feels very different and uncomfortable, thanks
