What’s the technical basis for a hard lump in a muscle that gets painful after exercise? What you’d typically call a knot, I suppose.

And what can be done about it besides poking it and making it hurt?

They are simply bits of muscle that are sticking together for whatever reason. Could also be scar tissue or a variety of other things.

What can you do to stop it hurting – strengthen the muscle that opposes the action of the muscle with the knot in it, or break down the adhesion by massage, dry needling or whatever other sort of voodoo you’re into.

Gastrocnemius

Google ‘trigger point’ and also ‘MSF using foam roller’
Lots of good info out there.

I’ve been foam rollering. Sorted my knee pain really quickly (just did 7 miles with no pain!) but my calves have become sore again post exercise which they haven’t been for ages.

However I did just run a very long way for me, double my usual long run and lately I odn’t even do that very often.

Whereabouts in your calf? A lot of what appears to be gasctroc pain is actually coming from the smaller muscles that run either underneath or beside gastroc.

So if you sliced my calf in two perpendicular to the bones, just through the widest part and looked at the cut-off lower leg part from the top, if if my foot was 12 o’clock it’d be about the 8 o’clock position.

Or, on that diagram, right where the SOLEUS label is pointing to.

Foam rollers are your friend mate, give one a try.

Poke it, stick some heat on it, take your choice of anti-inflammatory and see what it’s like in a day or two. Alternatively try some combinations of toe pointing and turning your ankle in or out (as if you’ve gone over on it)

These are the business.
You’ll find knots you never thought you had.

Stick looks interesting – is it really better than a foam roller though? Also my top tip after rolling/sticking – always stretch properly. Seems to massively increase the effectiveness for me.

Good, those are the things I’ve already been doing 🙂

Took ibu, seems to have helped marginally, but it’s hard to know how well it’d have calmed down on its own.

Strangely enough it doesn’t hurt much when running.

A glass of Brandy and a visit from the Thai Massage lady who advertises in the local phonebook / phonebox will make you forget all about it.

Or, get a Sports massage. If you haven’t had one before, do not be under any illusion that they are relaxing, but it will help your issue.

That’s because it’s warm and slippery when you’re running. 😉

If we’re going for shameless plugs if anyone wants to pay me for sports massage in Edinburgh, I have qualifications in that.

Rumble Roller. Works on my calves. Extra firm, natch…

Rolling pin, foam pipe insulation, bit o tape to hold it all together….ta da….ghetto foam roller/american stick*
