wonky shoulder

I’ve got a pointy bit on my right shoulder that’s been there for a long time now. I crashed a car way back in 1993 and I spectacularly rolled it down a hill. The seatbelt, whilst it probably saved me from something, snapped my clavicle and it healed a bit weird with one of the pieces of broken bone sticking straight up. Up until now the only problems I’ve had with it has been in the winter when the cold and damp air makes it ache a bit and it probably ruined my modelling career – I’ve recently discovered however that shouldering a ‘cross bike places the top tube right on that pointy bit of bone and it’s bloody agonising after about 3 seconds. A bit like someone squeezing your elbow betwixt finger and thumb. So…I need to get into the habit of shouldering the bike on my left, which places the chainrings a bit awkwardly next to my ribcage…
