I took Bactrim DS for a while. I had a lot of herxing, including headaches, stiff neck, head pressure, eye and ear pressure, shortness of breath, insomnia, anxiety, irritability and forearm, leg and other pain. There could have been other increased symptoms too.
2 pills a day was too much for me at first. So, I ended up cutting my pills in half and taking 1/2 pill with breakfast lunch and dinner until I felt I could take 2 pills a day. That helped me work my way up.
It sounds like you could be herxing too. You could also have increased inflammation from working out.
I hope you feel better soon!
