My Knee Has Been a Problem Since 2019: I Spent Eight Weeks Testing a Magnesium Cream on It

I had a partial meniscus tear in 2019. The surgery went fine, PT went fine and then I was left with a knee that just… never fully came back. It aches in cold weather, hates stairs and flares up after anything longer than a 45-minute walk which is annoying because I like long walks.

I’ve been managing it since then with a rotation of PT exercises, one of those diclofenac gels when it gets bad and a compression sleeve for hiking. I wasn’t looking for a miracle, I just got curious after someone in an online running group mentioned using magnesium cream for knee pain as something their physio had brought up offhand.

I found the product through HiRelief, which had a comparison of a few different options. I ordered one, started using it and kept notes for eight weeks.

Weeks One And Two: Nothing, Basically

I applied it around my knee, not directly on the kneecap but the muscles above and below it, plus the inside edge where I feel most of my discomfort. Morning and evening, about two to three minutes of actual rubbing each time. I noticed a mild warmth after applying it.

Week two, the morning stiffness seemed slightly less, not gone. I could get up and walk normally faster than usual. I almost wrote it off as wishful thinking.

Week Three Is When I Started Paying Attention

My knee has this background hum of aching that I’ve kind of gotten used to. Like background noise you stop noticing. Around week three I realized the hum had gotten quieter. That’s the only way I can describe it. It wasn’t sharp relief, more like… the knee stopped being the first thing I thought about when I sat down.

I also had a session with my PT that week. She said my quad engagement was better. I hadn’t told her I was trying magnesium cream for knee pain. She just noticed the change on her own.

The Bad Week

Week seven, I did a longer hike than I should have, about 9 miles with significant elevation. My knee flared, not a disaster, but it flared. What surprised me was the recovery. Normally a flare like that would leave my knee grumpy for three or four days. This one was mostly settled by day two. I can’t say that’s definitely the cream. But it was faster than I expected.

Where I Landed After Eight Weeks

The background aching has dropped enough that I notice it less. The morning stiffness is shorter. I haven’t had a full flare since week seven. My PT says the muscles around the joint are responding better. None of that is dramatic. All of it is real.

Using magnesium cream for knee pain isn’t replacing the PT exercises or the compression sleeve. It fits alongside them. The thing that surprised me was how localized it felt, not a whole-body thing, just that specific area. My PT explained it’s probably about the muscles supporting the joint settling down, not the joint itself. That makes sense to me.

I’m still using it, still sourcing from Hirelief. The version I have is a higher concentration than some others I looked at which I think matters a lot because what I found early on was too weak to do anything.

Final Thoughts

If you’re dealing with a knee that’s been problematic for a while and you’ve already got the basics covered, PT, appropriate exercise, sensible footwear, adding magnesium cream for knee pain to the routine is a low-effort thing to try. It won’t fix a structural problem but for the chronic low-level aching and the slow recovery after a hard day, it’s been genuinely useful for me. Two to three weeks before you notice anything real. Don’t quit before that.
