I am in the category of never getting colds. This cream is usually used for genital warts I believe but as I have such long standing veruccas they have prescribed it for them have used a very small amount of this cream on a small wart on my hand and one on foot, leaving others for now wary of side effects yet after only two applications I have a cough, cold and sore throat. I always get side affects but am amazed this tiny external application is having such a marked affect. It is an immune modulator. I know it is this because there is always a reason for a cold - 2 years ago was my last and that was LDN. Also i always feel better the day before a cold but I didn't with this just a bit crappy like I had done since the first application of this. I am just curious - is this a bad thing, it is one of the listed rarer side effects but if I don't get colds and this can give me a cold is it still a bad thing because its messing with an immune system??? Sorry if I have posted this in the wrong place, as i say i am full of cold and even muzzier headed than usual.
