Thank you! Yes, I can still hobble around. Today is actually better than yesterday. I only have mild bruising and discoloration. I hope that it doesn't take me 4 weeks to heal!
Stay off of it while it hurts. Use cane or crutches as needed. Don't get back onto it too vigorously too soon. When I pulled my calf at age 51, I used crutches and a cast boot for a couple weeks. It was feeling fairly good in 4 weeks, so I went to play soccer again and promptly pulled it again. When it was bad, I could not push of my toes at all, so the cast boot was the only way I could put weight on it at all. If you can "walk" with a cane, your strain might not be too bad and you might be up and around fairly quickly.
The amount of discoloration will be a good indication of the severity of the strain. Also, for a severe strain you will be able to feel the gap in the muscle where it tore. A visit to a doctor to get a referral for physical therapy would be helpful for getting going as quickly as possible. Until then, continue RICE, massage it to work the junk out of the area, wiggle your foot in circles of all sizes and directions without causing pain. Add strengthening and stretching very cautiously.
