I have been getting these injections for a couple of years, and love my doctor- and will address this with her) but wanted to reach out for experiences from others. I started taking Bactrim and Tramadol for a serious kidney infection. I will be on the Bactrim for 8 more days. My appointment is in 8 days. Are there any serious side effects when taking these drugs and getting the injections? Should I have another month to make sure the prescribed drugs are out of my system?
