Fell off bike. What can I do to soothe the abrasions?

Calendula lotion. You can bathe the abrasions with calendula lotion -- you can find this at whole foods or other health food store. Use the kind without alcohol in it, or it could burn. Calendula is made from a plant, which can speed your healing. I would let the abrasions be in the open air to make scab, and then do not disturb. Your body knows what to do.
