I went long boarding 3 days ago and ended up falling and skidding on the hard ground on a down hill. Both my knees was scraped and both around the same size as a ping pong ball. I went home and cleaned it with water and bandaged it up until later that day when I sterilised it and applied some polysporin. The next day I did the same thing and also showered with it and rinsed off the medicine and just tried to keep it moist and clean. It still continuously had cream/yellow colored pus coming out and the joint was aching when I walked. I woke up this morning with the wound on my right mostly yellow colored and I didn't know if it is infected or not? Can someone please tell me or message me for other details?

I am 28-year-old male. Three to four years ago, I started noticing gray hair. Currently, I have significant number of gray hair strands in my scalp and beard. I have no family history (genetics) of hair graying. I have never used any cosmetic product in hair. I was an infrequent smoker (upto 7-8 per week) but quit six months ago (cold turkey). I admit have some job related stress. I have been diligently drinking amla juice for few months now but have not noted any significant benefit. Kindly tell me what could be the possible reason behind this. Which medication should I use? Is it possible to reverse gray hair to black hair?

From where can I order glo blanc advance tablets 600 mg . It is not available online on any app or pharmacy.

There was a old small pimple that was filled with pus...I accidentally poked the Pimple and the pus came out with a little bit of blood... . . But NOW I'm worried of getting a DARK pigmented mark in that area... . . Should I apply neosprine/betadine so that the wound gets healed properly and if yes which one would be better the antiseptic powder or the ointment... . . What can I do to protect and avoid any pigmentation in that area...
