Dear Vin,
Actually, I am a little concerned about your groin area. Try to get a call in and talk to someone about this. You might do a little googling on your own as many doctors do not recognize some of the strange responses to BCG's. At least my doctor didn't.
About the clavicle, my right shoulder became LOCKED as a result of a BCG triggered arthritis. Actually, come to think of it, my arthritis did not show up until 2 weeks after the 9th treatment.
I'm not saying that you have arthritis, but, my Doc, when he finally surrendered to the fact that my arthritis was BCG related, told me that BCG's were like aspirin, there is a range of about 5,000 different responses to the treatment.
Report EVERYTHING to your doctor and have it documented.
If you can't get the Doctor this weekend, then call on Monday and ask about the groin area, as that one is a new one on me.
Take care,
Rosemary
