I was hesitant to post this, thinking that this was a minor idiosyncrasy only specific to my situation. But I just saw a query about Bactrim, which made me think that it might be worthwhile to share this info.
This is also in relation to the recent postings on whether or not inflammations can cause, or at least exacerbate RLS. I was on an anti-inflammatory diet for almost a year, but it sadly made no difference to my RLS, so I was skeptical. But a recent discovery made me realize that there IS a relationship between RLS and inflammation.
I had hand surgery last month, and the recovery has been long and painful. Because I don't tolerate strong opioids l, I had declined the Oxycodone prescription that was offered me. Since I take Codeine-Tylenol for RLS, I naively thought that that would be sufficient for my post-op pain. Well, I was wrong.
One recent night, I was having excruciating post-op hand pain AND horrible RLS. Although Codeine-Tylenol usually controls my RLS, it was totally useless. In desperation, I got ice packs for my hand, and about 10 minutes later, my hand pain subsided, along with my RLS!
My takeaway is that ANY unrelated inflammation in the body can exacerbate RLS. So, if you have a UTI or pneumonia or anything that requires you to take meds, you might consider the possibility that it may not be the meds, but the illness itself (or the inflammation caused by the illness) that's causing the RLS to worsen.
Just my 2 cents worth!
