I did similar,extremely painful at the time,iced,Ibuprofen,etc,seemed to get better,but still very painful to ride.
six months later,got that bad that I could’t sleep,or get up stairs to go to bog.
went to Docs,told to go home and have an aspirin.
two days later,pain was excruciating,went to A+E,fantastic service,seen in 30 mins,specialist called,diagnosed broken knee cap,confirmed with X-ray !
saw consultant in 48 hours,operated next day,as emergency ,three pieces of bone removed!!!
moral of story- don’t bother with the quack,get to A+E,don’t take no for an answer,or be told to MFU.
