I understand you’re not a medication person.
Lots of people aren’t. But as I tell my patients, there’s a time and place for them, and this is one of those times! Low dose of ibuprofen won’t give you the anti-inflammatory effect. You have to take 600-800mg every six to eight hours, with food, round the clock, in order to see some improvement. That’s why the cream would’ve been good for you, had it worked - it goes right to where you want it to go without possible side effects elsewhere (usually). Help the medication along by elevating your foot while resting, and putting some ice on it, as well. Just use a ziploc bag with some ice cubes and keep it on as long as you can tolerate it, taking it off and putting it back on if it gets to be too much. Unfortunately, swelling in structures isn’t very easy to get rid of. It’s a big problem on a foot, too, because a) you have to keep using it in order to walk, and b) it’s hampered by gravity - fluid settles there naturally. So you have structures that are inflamed in the foot itself, and then fluid can also settle in around the tissue, so double whammy. I hope this has helped. My thought with a PCP is that they might offer you a steroid and XRay the foot, as well as a general check up to see that there isn’t more going on than just “overuse“. I realize that isn’t easy for you to do, but if you continue to have pain that hampers your ability to walk, then it’s important.
