X-rays sort of confirmed fracture of 4th rib. Followed Doc's recommendation to take Tramedo for pain relief. Big mistake - after taking 2 tablets was as sick as a dog. Was nauseous and groggy for next 2 days, and the chest was no less painful than before taking them.

Long course at Whiteman Park, gps 8.73km. Tripped about 1km from the finish and done some damage to right upper chest - probably a cracked rib going by the amount of pain.
