Pulled/Strain/Torn Calf Muscle ?

If it was 3 days ago and you are contemplating putting weight on it then it was not a tear...most likely a strain.  Which is good news.  Also if it's a tear you will typically see a hematoma forming in the calf. 

My experience: RICE method is helpful and massaging the area after 4 or 5 days (and ibuprofin).  It shoud only put you out for about 10days or so.  Def stay off it until then...will help heal completly and much quicker.  These things tend to keep popping up if you take a short cut in recovery. 

See this site for some general info...and there's always that Doctor thing but the only way they will be able to tell exactly what is going on is MRI...so depending on your insurance that's either not worth it or it's just a simple appointment to get all figured out.

Quick question.What do you think about swimming again after a few days?

After 1-2 weeks of rest will come very passive stretching, then more active stretching before returning to light exercise.

I've had on and off recurring calf and Achilles problems for the past several years.  I recently stumbled upon a treatment protocol that has so far proven very effective for me.  There are a few books written by a massage therapist who has had extensive experience treating all sorts of repetitive strain injuries, and she has developed methods of self-massage treatments.  She also has a forum on her website where you can post your specific problem and she'll recommend a treatment protocol, referring to treatments as described in her books.

Here's her site:  www.julstro.com

You might search around on her forum as you may find posts from others who have very similar injuries to yours.

In my case, based on her experience in working with many other athletes, she suspected my calf problems are actually caused by several areas where I have muscle spasms (aka. trigger points) causing my pelivs to be rotated forward, putting pressure on my sciatic nerve, which causes my calves to go into spasm.  In the past I'd always just tried to treat my calves themselves, and after some rest and recovery I'd be okay for awhile, then, "BAM", one or the other of my calves would bring be to a halt again.

Since I've started treating various muscle spasms in my my quads, hips, glutes and lower back, as well as my calves, I been able to run without my calves going into spasm.  In fact, I've been running quite a bit...ran 60 miles this past week, which I think is a new max weekly mileage for me).  It requires regular maintenance on my part, but I've been happy with the results so far.  I never could have imagined that my calf problems were largely being caused by muscle spasms in my quads and hips.  Whoda thunk?

Anyway, just thought I'd share my experience in case you find that it may help you too.  I have no financial interest in it.

(BTW, if you wanted to get one of her books, I recommend you get Treat Yourself to Pain Free Living.  She has a book specifically targeted to triathletes, but frankly it doesn't have anything of use that the Pain Free Living book doesn't also have, and Pain Free Living is more up to date.  She also tends to refer to specific pages in Pain Free Living for treatments on her forum.)
