I don't play a paramedic on TV, but I have rolled as an EMT a time or two. So here's the cure 100 out of 100 E.R. docs agree upon: take 158 grains of Pb 50 times a day and administer via a 2" to 8" .357 inch bore "needle" to the appropriate target until the web of your shooting hand just begins to tingle, going numb is an overdose condition. In the event of overdose, recommend you taper the dose by administering 32 grains of.22 Stinger Pb, via a nominal .224 bore "needle," continue until the target dose is acheived, most likely at 25 yards. Excellent results have been acheived using a 4" "needle" administered by a Model 18 rotating cylinder device.
Should you suffer side effects of any of the above doses (usually characterized by pain accompanied by numbness to the web of the shooting hand), clean your revolver immediately and return to the safe. Begin an immediate regimen of Hogue, Uncle Mike's or Pachmayr rubber prophylactic devices and sheath your grip frame until either symptoms subside or continued use shows no relapse of side effects.
Addiction is a very real possibility when taking your Pb dose and can occur with the use of any "syringe" the JKLN or X, the Python, Diamondback and the single action. So, there is no cure. Prognosis is excellent as the condition is uncurable and will eventually result in a lifetime spent applying Hoppe's No. 9, Break Free and RIG ointments, PRN.
I trust this advice will be of assistance, may your condition be chronic and your safe contain many rotating cylinder instruments to ease your pain.
