Less than 2 weeks ago, I switched my generic Cymbalta to a more convenient pharmacy. As the days went on, I noticed that my right hand, right leg at times and even the right side of my face felt tingly. In the meantime, I developed a case of intestinal flu so I couldn't even try to take my daily meds. I only took my blood pressure pills on Friday and went back to taking the generic Cymbalta this morning. For the majority of the morning, my mouth was tingling. My blood pressure is fine, I have lost nearly 30 pounds in the past 4 months. I'm wondering if the generic Cymbalta which is from a different manufacturer is causing my problem. I plan on calling my family dr. on Monday but in your opinion, do you feel that I may be on the right track that the generic Cymbalta could be my problem? BTW, I'm checking my blood pressure regularly and it's fine.
