You ought to get that seen to, it sounds unpleasant.
But if it turns out to be as bad as it sounds (prolonged contact with the dissembling chancers* pimping this sorry scam has to be risky in terms of exposure to -ahem - contagious diseases) whatever you do, don't take briliacidn.
Not only is it unapproved, but it has been shown to slow time to recovery, and chances are much higher than 50/50 that it will give you a nasty hypertensive spike and/or peripheral neuropathy.
Oh, and it won't work either.
*I initially mis-typed "chancers" as "chancres", but that's pretty accurate too.
