Otezla - Muscle cramps?I'm on my 7 day and I'm having muscle cramps in my calves. Is this normal? I?

I'm on my 7 day and I'm having muscle cramps in my calves. Is this normal? I have migraines so it's hard to tell if my headaches now are from otezla! No nausea so far but going to bathroom often. I just came off humira so I'm praying this works. I can't tell if it's working or not yet? I'm just concerned about the cramps in my calves! Yesterday was my first 30 mg dose.
