Hi and , and thanks for being engaged in this conversation. It's an interesting topic!
I will say that medications may be associated with all types of side effects. Some may be common, while still others may not only be less common, but often times not known until someone steps forward and reports them.
I say this from a wealth of experience with many patients and various medications. If, as each of you suspects, the issues you are discussing (muscle cramping), turns out to be so - you will certainly want to discuss it with your respective physicians.
I would suggest you keep at it until a diagnosis is reached and a solution found. If the medications are helping then it becomes even more important to find a solution to the side effect concern.
Please do check back and let us know how this all turns out for you.
Good luck!
