Common warts on my hand?

I've been applying Salicylic acid on my warts on my palm for five days now. I wasn't brave enough to file down the weakened wart/skin until tonight. I used the edge on an emery board to push off the lose skin/wart after I showered. I was able to take off a lot of affected skin/wart. I took off some unaffected skin that was too close to the wart (which had been covered in salicylic acid). I'm scared of filling down the wart because it seems like the prime way to spread it...The brand I'm using is called Verrumal Solution and has other chemicals that are supposed to keep HPV from spreading and such, but still, very nervous about spreading warts to other parts of my body.

How often should I be filling down the wart? The reason I tried it today was because tonight, the wart and the surrounding skin seemed to have been lossened enough. Should I be filling down everynight after shower? Or should I keep applying the solution and file down when it seems loss enough again?

Help please!

And when would I know all the warts have been eliminated? After I filed it down, I still had black dotted irregular looking cells underneath what had been filed down. Are these still warts?

If you can bare the pain goto the doctor and get them to use nitogen oxide to burn the warts off. It will keep coming back its a virus within your body.

You won't spread it. Continue to use the medication as directed. It could take up to a month for it to go away, though. They're not slow to grow so they're not slow to go away either.
