<s>[INST] Can you please advice the reason for this? hi I was diagnosed with probable Multiple Sclerosis 3.5 years back. Recently since last one week I could sense some numbness on the right side of my ear with slight pain in the right ear. The numbness has decreased but I can find stiffness in my right hand can you please advice? [/INST] Hi, Multiple sclerosis can cause the neurological symptoms, but it is more at the lower limb side, upper limb involvement is less common. Ear pain (Nostalgia) may not be due to multiple sclerosis, but it could be due to impaction of wax, and it needs to be ruled out. For the upper arm stiffness cervical spondylosis could be the cause, but it may not be due to multiple sclerosis, Hope I have answered your query. Let me know if I can assist you further.  </s>
