A couple of years ago, my stomach and lower chest muscles started cramping out of the blue after a prolonged stressful time. I called a doctor, who sent an ambulance because the pain was close to the chest. That lead to being admitted to the cardiology department and going through a lot of testing, ending with a CT scan of my heart. The conclusion was "low non-obstructive coronary disease", so probably what any 40-something would be diagnosed with if you gave them a heart CT.

The waiting for a result on the scan results lead to my stress levels skyrocketing to the point of getting diagnosed with benign fasciculation syndrome.

Since then, I've been hospitalised three times by ambulance because of the same spasms/cramping in my abs. When it happens, it's lasted anywhere from 40 minutes to an hour and a half where my muscles are just hard as a rock. Then, at some point the cramping stops and I'm left with sore abs for 2-3 weeks, during which I'm scared it'll happen again.

Then everything seems fine and I forget about it until it happens again out of the blue half a year later.

I have a follow-up with my doctor next week and we'll look into alternative causes since my potassium levels have been a little bit low when tested during the hospital stays. Other than that, all other blood tests were fine except ALAT liver enzyme levels each time which went back to normal when re-tested.

Due to the stress, I've had a number of panic attacks which are especially bad since I'm worried about cramping too during them because of the increased muscle tension.

Has anyone else experienced cramping this bad because of stress/anxiety? I've had muscle cramps in my calves and hamstrings after exercise before and this is a lot like it - but never for an hour and a half.
