I, too, find Bonesmart helpful. I have always been sensitive to weather changes, especially drops in barometric pressure (hereditary osteoarthritis and bursitis). Last year (April 2018), I had a right Partial Knee Replacement. Planned to do the left PKR this May, but then tore a rotator cuff tendon, and had to move the knee up to late March. Had the RCR in late May. So I agree about the cumulative fatigue after surgeries. I also am ultra sensitive now to the drops in pressure, so much so that I started researching online, which is how I found BoneSmart. At my next appt, I asked my ortho surgeon and he said about 40% of people are sensitive to weather changes, but virtually all people who have bone surgery are very sensitive afterwards. Thankfully, he said it decreases over time, but it takes about 2 years. So I have a barometer app as well as weather apps, and when the drops are due/occur, I take pain meds before/as it drops, and I eat non-inflammatory food until the pressure goes back up. Salmon or tuna, but not shellfish or tilapia. (I don’t eat meat or pork ever; might rarely have turkey but only if I need it to increase serotonin. ) Whole grain pasta, but no white pastas. No dairy (a bit of cooked cheese say in pesto sauce is okay). No refined sugar. No nightshade vegetables. I don’t ever eat these either because of my osteoarthritis. White potatoes are the worst for me.
So I believe you are right that the weather affects your knees. Thanks to you and everyone for sharing your experiences.
