Dear colleagues.,happy NY'2012.,nice to be connected with all.,a gentle reminder.,plantar warts are planted deep into the plantar sole of feet usually by some form of pointed punctre which is the reason why you have to pare or scale the wart before you can see the nest of warty cells which typically appears as black dots'',
If you want to hit this you have to expose this site before you attempt to treat this with what ever ablative procedure.,physical or chemical.,so please try to expose the nest of black dots the next time around and you can expect better results.,reminder again the virus sticks to an epidermal cell at the top and cannot stimulate the pts.immune system to fight back-I was indeed impressed by one of our colleagues suggestions to implant some of the viral particles put into formalin'into the thigh skin for this indeed could serve to stimulate the pts own defence,,,seenikatty malaysia.
