Standing up holding a small item ready to put it in the shopping cart and I experiened lo lose of control and had to hold tight on basket handle. And then i was in extreme pain and found it difficult walking unless pushing cart to take the weight off. Had to be wheeled out in a wheel chair. My husband was with me. Since than over 3 hours ago I need help getting up and I am holding on to areas while walking slowing. What do you think? I m 77 years old weigh 125 and in very good health.
