This is not asking for medical advice, more like runners advice.
So I’ve been training for a marathon for a few months and the running has gone pretty well. Up until last weekend I had been training in some North Face trail shoes. I know they aren’t made for road running but they were comfortable and didn’t give me any problems. I had run 4-5 13+mile runs in them with nothing more than mildly sore feet and some small blisters at the end.
So my wife told me I needed to get out of those 6month old trail runners and get into some proper running shoes. I said OK and went to the Running Store. They fitted me for shoes (neutral, normal shoes) and I got some Brooks Glycerine 8 shoes. They felt ok so I took them home and took a quick 4 mile run to try them out. Felt ok, though they were MUCH squishier than the trail runners for obvious reasons.
So last Sunday I did a 15mile run (furthest ever) and felt great at the end. Feet felt good, though not $130 better than my old shoes. Toes were a little numb but I think that was from new socks and shoes.
I ran 4 miles a couple days later and felt fine.
Then about 5 days ago I was putting on my pants and felt SEVERE pain in my lower calf. Like someone was cutting my leg off at my lower calf. I hadn’t felt this before. It hurt like hell. If you look at a picture of the back of a leg it’s right about where my Achilles tendon hooks up to my calf muscle. I’ve felt this about 10 times since then and here are the motions that cause it every time:
Let your foot hang limply. No flex in the calf at all. Don’t engage the calf muscle in any way. Lift the leg up (like you are putting it on a coffee table). It also happens if I let my foot hang loose and pull pants on while standing up.
The strange thing is that I feel 100% fine when walking, running, climbing stairs both up and down. I can rotate my foot at the ankle all day and night and not feel the slightest twinge of pain. It’s only when I let my ankle go limp and raise the leg straight out.
The problem is that when I DO hurt it hurts f’n BAD. Burns super bad. It FEELS like my calf but on a diagram looks like the top of my Achilles. I laid off running for a week and went out for 4.5 today and it feels fine, no pain, except when I go through that motion described.
I don’t want to blow out my leg 2 months before the marathon (1st ever) but it also feels fine to run on.
What is wrong with me? I think it may have been those shoes as that was all that changed. Any ideas?
