Prayers for healing inbound!
Neil,
So glad you are ambulatory and that nothing was life threatening.
Insurance companies know the drill and since the other guy is already tickets "at fault", this should be day for the insurance companies to manage.
The problem may arise if the van's insurance isn't enough to cover your combined medical expenses or damage to the bike. THEN lawyers need to be involved.
Best of luck with that.
I hear an "anti-microbial" fluid, sold under the generic name "scotch" sometimes helps minor bruising.......
Cheers,
Steve
