May have swallowed part of a chicken bone, eating too fast. could feel it irritate and go down. but no pain now. what to do?

Nothing to do: Don't worry about it. Just eat a normal diet -- the bone probably will pass without difficulty or harm, probably without you even knowing it. Of course see a doctor if you develop abdominal pain, nausea, vomiting, blood in stools, painful defecation, or other problems. But all these are unlikely.

Some basics: If the foreign object made it into your stomach & was not caught in your throat it will pass down the GI tract & out within a few days. We have plenty of experience with toddlers eating strange objects that do the same. Consuming cut okra soon after can help form a soft congeal around the bone & soothe its passage but is not required for success.
