Rats!!! Double Rats!!!
Thanks for posting the pics. Most of us have been there for one reason or another but that does not make it any easier for ya. Remember that road rash almost always gets infected. Here is some things I have used to get a seedy recovery from road rash in my patients.
Skintegrity Hydrocoloid
Telfa Non-adherant pads
3M Medipore H Soft Cloth Surgical Tape - 4 Wide by 10 yd Breathable
Cut a section of Telfa pad to the size of the skin injury. Cut a section of tape 5mm larger then the Telfa and then mount the Telfa to the center of the tape. Put a thin layer of Skintegrity over the Telfa pad then place the dressing over the injury. You can change the dressing out every other day by soaking it off in the shower. Be gentile with the new skin forming under the pad. I recommend using Shaving Cream to clean the wound before doing the dressing changes.
As for the collar bone... That's a time thing. Be careful, no stress, good nutrition, think good thoughts... AhhhUmmmm....
