<s>[INST] I had bells palsy 2 yrs ago and it didn t heal! Now when I get hot my eye draws shut my right side of my face pulls up, the right temple hurts bad and my left arm hurts and starts to tingle!! It s weird that all this happens as soon as I walk outside when the temperatures are high!! [/INST] Hi, The onset or worsening of neurological symptoms involving cranial nerves with heat as a trigger is called Uhthoff's phenomenon. It is not clear to me that the Bell's palsy is exactly tied to what is happening and in fact, there is a chance that you are not suffering from true Bell's palsy to begin with but rather a central nervous system mimicker. My recommendation is that you speak with your primary doctor and ask to be referred to a Neurologist for the purpose of going back and relooking at the diagnosis of Bell's Palsy in the light of your neurological symptoms which are exacerbated by heat. There is a good chance the neurologist will order tests and studies on you such as an MRI of the brain and cervical spinal cord with Gadolinium contrast. This may disclose the reason for these problems. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Dariush Saghafi, Neurologist </s>
