OTC that contain anti-inflammatory (methyl salicylate) you can put right on
your foot.

Salonpas --- Read the label in the store, to make sure they are the right ones.
Some are only with menthol---and those are not as good.

They work wonders, for localized pain like in a foot. I use them all the time,
and buy them in bulk at Costco.

One box locally should cost you around 3-4 dollars, for 40 patches.

Do not get BenGay--they are not the same.
RiteAid carries them--you will want the small ones.

the one I recommend is the first picture on the left showing products on that website. I'd be lost without them.

We went over the Mobic issue on the Medications forum.

RiteAid typically carries them. They are often not prominently displayed however.

Once I had a huge swelling on my Achilles tendon, which hurt like the devil.
I went to my podiatrist and they said--- Motrin. Well, that wasn't much help.
Then I found some samples when Salonpas just came over here to US and
took some from work. Using one patch a day for 7 days completely shrank the swelling and it went away... I had that agony for months with no relief! So I am a big fan of them, and everyone I recommend them to loves them.

You must give it a try. Once you open the pouche, keep the unused ones in a airtight ziploc baggie to keep fresh. I use them on fingers and toes too.
You can stack them on your back for larger areas.
