Actually, GH absolutely DOES affect swallowing in some people. Did you read the info in the link?
It sounds like you need some clarification from your doctor, to find out exactly what he's thinking, what he's ruled out, and what his plan is. It's a little alarming that you're not aware of why you were prescribed the medications you were, and that you're not aware of what the medication is typically prescribed for. Olapex, also known as Zyprexa, is actually an atypical antipsychotic medication. It's a pretty heavy hitting drug that comes with some considerations.

No, I'm not a doctor. I'm a registered nurse, but like any other member here, we're just offering you some suggestions. The internet isn't the place to seek a medical opinion. There's never a substitution for IN person medical care, where a doctor can examine you and look at the whole picture, with your medical history and diagnostic test results.
We DO have expert forums, you can browse the list and see if perhaps any of them meet your needs. Some of the expert forums require a nominal fee to post your question. Here's a link to the Expert Forums list:

I cannot stress enough that you need to ask questions, find out what it is your doc wants to Rx you and why, and then do some homework about the risks versus benefits. You must be your own advocate, and not just blindly trust your doctor. I would recommend making a follow up appt with the prescribing doc, and soon.
Good luck to you. I hope you find some answers, and some relief. Update us when you can.
