You have most likely damaged some or all of the drive side spokes that have the heads facing in and the elbows out at the hub. The right way to fix this is to replace all damaged spokes then true and tension the wheel. A simple truing will only solve your problems short term. Any damaged spokes WILL break. Take it from someone who tried this as a cheap fix before I knew anything about wheels. It is only a matter of time before this wheel will leave you stranded - I wont say unexpectedly. If you do not have the tools or knowledge to do this repair, do yourself a favor and take it to a competent person.
