I think the reason he is getting headache’s is that they eat alot of foods with salt which they need but sometimes they take in too much, That will cause headache’s the belly pain is from the meds they are very hard on the belly.That is why they say to take it with food or milk. And also I think if your son says he wants to be back on the other meds you should really think about that he’ll know better then anyone else how he feels. You also should ask them to do blood work as soon as they have room to take you. I’m sure endo will put him back on his other meds when they hear how he feels.Inless the other meds weren’t working the way he needs them too.
