Charlie horse with calf pain hours later

Co
So I am 22 weeks pregnant and waiting on my obgyn to call me back, but around 2am I woke up with a severe charlie horse. It lasted about 5 minutes until my husband had lifted my foot upwards and it stopped. Well I could not get back to sleep and the pain is still there in my calf. I have tried walking (more like limping), stretching, massaging, proping it, and icing it. But nothing works. I followed advice from my mom and started drinking a lot of water since I have been up and I ate a banana for potassium. Anyone else experience this? What helped you?
