Hello, I was wondering, I haven t been to the doctor yet, but I ve had three different joint issues in the past month one in my hip, pain, sort of feeling of dragging my leg. Also, then a week ago woke up with both my knees hurting terrible, fine when I was walking but, if I tried to bend them... Pain. Lasted about two days.Then that went away too and then today my left foot started hurting when moving it, it s the top of my foot and inside, with all three events I can feel the heat coming off the area. Also last summer, it also happened, I clean house so I m always active, but I came home after working all day and took my shoes off and sat down, when I finally got up to walk, oh boy, pain swollen, and the next morning was really bad, swollen could hardly walk on them, went to the doc for that, but he didn t know. And then it went away in a couple days until all this. I m 48 yrs. Los 5 7 1/2 and 130 lbs. work every day cleaning, sometimes 5 days a week, 6 months a yr. I clean 7 days a week, just wondering if you might know ......something?
