I have developed frozen shoulder and some other problem with my elbow that's pretty painful and my regular Dr gave me naproxen cr to take twice a day. When I take it with Trokendi XR, it makes my feet tingle off and on throughout the day. I know this can be a side effect of Trokendi on it's own but in the two years of taking Trokendi, I never had this problem until I took it with the high dose of naproxen cr. I asked my regular dr if it was a sign of something dangerous by mixing the two meds together or if it was just something annoying I could just deal with. She said she doesn't know enough about Trokendi to know the answer because my pdoc prescribes it. So, for the past 2 days, I have been trying to get the answer from my pdoc. I can't get a freaking response. I mean how much effort would it take to send a 5 minute email answer back or text or return phone call??? I've asked for the answer 3 times now over 2 freaking days. I have to go to physical therapy tonight and my shoulder and elbow are hurting and physical therapy is going to be painful, the therapist warned me it was going to HURT. I need to take the medicine. But, I can't until I get an answer. And my reg Dr won't call anything else in other than motrin and naproxen works, I just have to deal with the tingling. I don't understand why the f.*#k my psychiatrist can't just answer the stupid question.
