Muscles locking up
I have looked online for info on my issues I am having with certain muscles and have not found much.
As of late I have not been eating a lot of food, and I workout a lot. I have about 3 protein shakes a day, and a source of carbs and a source of fat. All healthy, i.e. beans, oatmeal, rice, fruits/veggies/nuts. I am probably not getting enough carbs or protein, but I am trying to keep up and force myself to eat due to working out and needing fuel for my muscles.
Anyway, my calf muscles lock up if I work out and then try to run a comfortable pace for about 5-30 minutes. Sometimes within 2 minutes of running one of them will lock up and I have to stop.
Also, a muscle will sometimes lock up in my chin when I am trying to take a bite of something. The other day I was stuck with mouth agape for about 2 minutes because the muscle did not want to loosen up. A muscle in my foot does the same too. It leads to my big toe, and it happens pretty often. I don't know if I have a deficiency or if my food intake is too low. I used to eat french fries baked in the oven ALL the time, but since I have been trying to burn bodyfat and get cut up I have avoided potatoes, so I am losing iron. I've read magnesium is very important also in this situation, but I am not sure.
Does anyone have any insight?
