Hydrotherapy every evening and it will heal just fine... few squirts of Vetercyn also and it will heal quicker.
Mr. Mike is right, this is exactly what i've done with mine for quite a while and never have any problems.......dont hit the woynd full power out of a nozzle, just hit it with an open ended hose for 5-10 minutes a couple times a day and spray veterycin after.
