I remember watching a SciFi/Paranormal thriller kind of tv-series with a man that had a special gift. I remember some vague details, like glowing spiders as one of the problems he needed to solve in an episode.
Some more general memories: the main character always needed some kind of antidote or injections from some sinister person. Also, the intro sequence contained lots of biology closeups, like cells mutating or similar, with lots of glowing yellow highlights (but I don't know how much I got influenced by House's intro).
Sorry to be so vague - it's from when I was a child and I really don't remember much, except that I was somehow strangely attracted to it.
It very probably is aired before the year 2000.
