I'm so sorry...what an awful situation all around. I will keep praying for you and hoping you can get some relief.

I just talked to my boyfriend who has had many many bad scrapes in his day and he suggested the following.

Clean it out using alcohol (rubbing alcohol that you can get in the pharmacy). Do this several times a day...as often as the guaze is full. He said he uses the regular liquid kind but there are also aerosol sprays.

Use gauze over the wound. I know this part sounds painful and I don't know if you can do it or not because of the pain...but he said to try to pack the wound if it's deep to draw out more of the pus.

Tape the gauze down firmly so that it can really draw out the pus and infection.

He said if it is a really deep scrape that it could take a couple of weeks to heal fully...but cleaning it out several times a day is a must. He said you can use neosporin on it...but the alcohol should be sufficient in most cases and may make it easier to gauge how much pus there is vs cream.

That's about all you can do on your own I guess...all of which you may be doing on your own anyway...but I figured it might be worth asking him since he doesn't go to the doctor for anything really and I know he's had his fair share of first aid. Has two brothers and I take it they got into a lot of mischief growing up...not to mention sports injuries.
