Cramping can be so uncomfortable, especially when it comes on suddenly like that. Since it started after beginning the medication, it might be worth keeping an eye on and mentioning it to a pharmacist or healthcare provider when you can, (if you haven't already) just to get their take. I have heard that some asthma medications can cause muscle cramping for some people. Hopefully others can share if they’ve experienced something similar too! And in the meantime, I truly hope it eases up for you! -Kimberli (Team Member)
