if you have pain it COULD BE because it it boosting your immune system to do its job.
Also, the bone spur.... who knows....I'd be cautious about saying the medication is responsible. I have them all over my spine without the medication. it is common for post-menopausal women. it's kinda like wirey hair and facial hair growing after menopause - there are bone spurs! (osteophytes!) 😩 they don't necessarily do anything bad unless they press on nerves.
