I also have numbness with no pain in my left lower lip and chin. I've had it for about a year. In August of 2024 I was diagnosed with stage 4 metastatic cancer and had 10 radiation treatments to my head because I had a brain tumor from the cancer. Now I'm on Verzenio and my hands shake a lot and I have neuropathy in my feet and lower legs. I've also had many bouts of sciatica in the past, but that hasn't happened for a year. I think a trip to a neurologist would be a good idea. I've had many CAT scans, PET scans X-rays and MRI's since being diagnosed with stage 4 metastatic cancer. Verzenio has many horrible side effects, but it is definitely killing cancer cells. My blood test marker for CA27.29 started at 1698 last September, then dropped to 500 in November and my last test a couple of weeks ago was 177! Normal range is less than 39, so I'm not cancer free, but in 4 months that's very encouraging. Keep on fighting!!
