Hi there
It's great that you are finding relief without the rheumy medication.
My question is though,on whose advice are you taking the ibuprofen?
I know it is easy to acquire, but i do remember warnings on the packet to not have it as an on going pain relief.
Ask you local doctor if he can prescribe you something else and to help you with knowledge about a safe use of ibuprofen.
Can your local doctor also refer you to another rheumy?
These meds need to be monitored
Go see your doctor for advise
Take care and play it safe with professional help, you don't want some other problem that could have been avoided with more knowledge
