I woke up this morning with my right side tongue tip numb. The veins underneath appear slightly swollen. I am on Lasix 20 mg daily and use a c-pap at night. What would cause my tongue to go numb? It s like I have a thread caught on my tongue and the bit of sensation radiates from under my tongue, over the yip and towards the back of my mouth on my tongue top.
Thank you for contacting Chat Doctor. First thing which I Think in this scenario is a condition called Bells palsy where facial nerve is involved. Mostly this is result of some kind of viral infections. We have 12 pairs of cranial nerves. Facial nerve is one of them which carries taste sensation from the tongue. Each Half of the tongue is carried by one facial nerve. This nerve travels from the brain and supplies the face. When it is involved close to the face we see something like this. Please watch for eye closing issues, Chat Doctor.  I would suggest you to see a doctor and in case if they can't come up with the diagnosis please remind them of this. Take care
