Following horrendous cramp on Sunday night in my hamstring and then in my calf early hours Monday morning (same leg) it’s impacted on my Achilles, which is an injury I’ve been tackling over the last two-three months with physio support. (My Achilles has been sore for a long time before this).
My achilles has felt quite sore again after the cramp - so I booked physio today.
Despite continually working hard on my stretches to ease my Achilles pain and tight calf muscle, progress has been slow and felt like the cramp had set me back and I was worried that I was at risk of rupturing it if I’m honest.

Today Ive had ultrasound on the area (grateful for not having to endure a calf massage) but, Anna also discussed nutrients with me in my consultation.
I’d already thought about this. I’d re-ordered my magnesium as I’d ran out. I take electrolytes and I considered potassium (bought some bananas) but when we looked through my potassium averages (as I track) they were way to low. 😳😳😳
What I learnt today about potassium (thanks Anna)! is that it creates the electrical charge needed for nerve cells to tell your muscles when to contract and when to relax.
Without enough potassium, muscles struggle to fully relax after contracting, leading to tightness, cramps, and sometimes painful spasms.
The daily recommended levels are 2,600mg for women and 3,400mg for men. Mine were abysmal.
🍌 How to Fix It
It is recommended to load up on potassium-rich foods like bananas, sweet potatoes, spinach, avocados, and white beans.
It is also recommended to drink plenty of water alongside electrolytes (which I do) especially if you are sweating a lot during workouts or physio.
Thought I would share. Interesting isn’t it!
I’m not going to supplement these, I just need to switch my food groups.
