Lyme desease and the cure for Cat Acne

Hello,
I have a cat that was very very sick for about 8 months apparently Calici virus according to the vet and our research. In september he recovered, last treatment Colloidal Silver and gold (got it from Utopia). Then everyting was good until last month when he got Cat Acne, very bad, the lower lip vas very swalen. I treatet this with Colloidal Silver orally and washed the chin morning and evening with a face cloth dipped in a borax/water saturated solution (1 cup) with 1 teaspoon of hydrogen peroxide (food grade). It went away in days but needs to be rubbed so the black parts are comming out from the chin.
Now recently he is not feeling well, again the back paws but this time we found this site describing the Lime desease symptoms in cats and it seems that they are matching 100%, mostly the arching of the back.

"Better known as “shifting-leg lameness,” this condition is characterized by lameness in one leg, with a return to normal function, and another leg is then involved; one or more joints may be swollen and warm;
Other symptoms associated with lyme disease include:
Stiff walk with an arched back
Sensitive to touch"
We did not excluded the possibility of lyme the first time he was sick and we give him Ledum 1M but it didn't seem to help. I was searching and saw the Seasalt /Vit C cure for lyme, vit C I'm already giving him in lyposomal form, would it be ok to give some Sea Salt ? based on his weit that would be less than 1 g.
Any suggestion greately appreciated beside more tests, and vets that almost killed him and never mind what we spent.
