Sorry to hear you've taken a step backwards. I did that on sunday - after steering clear of running for a few weeks and doing most of the exercises I'd been told to do. It was pretty depressing. Having said that I still think that taking it easy is the best policy because I was feeling pretty good. I just think that I did a bit too much too it first time I tested my calves out. I probably could've been more disciplined with the stretching and strengthening over the last few weeks as well.
I was told to strectch very gently, 3 times a day - holding each stretch for about 30 secs, repeated 3 times. Stretch to the point of slight resistance rather than a little bit of pain. As far as strengthening is concerned I think it was just once a day but to do straight leg calf raises off a 2 inch step so that the heels go below horizontal. I've been able to do 20 - 25 raises but I think thats because they work the gastrocs more than the soleus (where my problem is). Having read up a bit more on this I think I'm going to try bent leg raises once my soreness has settled down as thats supposed to work the soleus more.
I was told to avoid running for a few weeks which would prevent another 'flare-up' and allow the strengthening to work.
It's frustrating to be restricted isn't it? Running is what I like most but I've only done that on a couple of occasions since my problem started in early April! I've made do with cycling and the gym so long as I'm careful. It's kept me in decent condition but dreams of running long distances feel a long way off right now.
Have you been to see a physio? I found it helpful in understanding the problem and how to put it right. I had 3 sessions and didn't get any change out of 100 quid but the way I look at it is that running is a cheap hobby, if it costs me £100 to get me back to it then so be it. Sadly there doesn't seem to be a quick fix though. My plan is to resist testing them out for a couple of weeks and to be really disciplined with the stretching and strengthening. Oh and I might even pray a few times too! We'll have to share progress reports now and then.
