BCG treatment and muscle pain/Arthritis

yes,  Ive recently completed 6 treatments and I am getting joint pains, knee, toes and fingers mostly not had muscle pain

I have aching thighs muscles and a propensity to cramp in my calves. I've had 9 so far.

I ignore the joint pain in my hands and knees as I already had arthritis in all joints in both hands and my knees. 

Yes you can and it's called reactive arthritis.

Morning Jenlids and thanks for your comments. Like you I’ve had BCG and been feeling like I’ve just run a marathon with muscle aches for no obvious reason. I thought it was due to walking around town but it persists without  any unusual activity. I have had arthritis in the past , maybe it’s an underlying reason. Best wishes, John.

I have just been referred to physio. Hopefully it helps :) 

I’ll be interested to know how you progress .

Just an update. Had a call from a Physio last Monday after 4 days of waiting so wasn't too happy about that. By that time it had eased somewhat so he told me to contact him if things got worse again. This morning I was in a lot of discomfort everywhere. Even lifting the kettle hurt my wrists and washing my hair was hard. He did suggest that if it got bad again I would probably have to have blood tests and he would contact Urology. I also contact my nurse and she said that it is still early days but if worried to contact gp. So ongoing still
