The conversation between human and AI assistant.
[|Human|] My tongue has felt thick and mouth filled weird off and on sometimes. Finger tips go numb and tingleing during sleep, even while working. Why or what may be going on with me. I m 53, white and really don t know. I have Osteoarthritis in my neck and Anklylosing arthritis in my back.
[|AI|]  Hello! Thank you for asking on Chat Doctor! Regarding your concern, I would explain that your symptoms could be related to different causes: - an electrolyte imbalance-thyroid hormone dysfunction- diabetes-vitamin B 12 deficiency-chronic anemia-peripheral neuropathy. For this reason, I would recommend consulting with your doctor and performing some tests to investigate for the possible causes: - complete blood count for anemia-vitamin B12 plasma levels-thyroid hormone levels-blood electrolytes- a nerve conduction study (electroneurography). You should discuss with your doctor on the above tests. Hope to have been helpful! Wishing all the best,
