Hi there ~
I understand your concerns. I believe that you had an adverse reaction from taking the pregabalin
and pavesca together. I also think that you need to stop taking the medication and alert your provider of the adverse reaction. It may be rare and you may be an isolated case. You might need to be started on different medications for the neuropathic issues for which you were started on the medication. Alternatively you might be suggested to start using normal doses to see if the edema subsides, but it would be your doctor's call. I hope you understand, and inform the doctor as soon as possible.
I hope this helps. Take care and have a lovely day!
