I am sorry you are suffering again.
At one point, you were getting some relief from Benadryl (diphenhydramine). Maybe contact your pdoc/pharmacist and see if it is safe to try Benadryl along with your current side-effect med? Please check it out fully with a qualified professional before trying it.
I hope you will contact your pdoc asap, as well, to get his advice.
I am so sorry!
I wish I could help.
