all symptoms seem to indicate MS, should I ask for an MRI?

I have been having terrible heat intolerance and I never go outside in the summer, if i do it will be very painful and I could start getting tingling in my face, or limbs.Another symptom I have is POTS it causes exercise intolerance and sometimes I cannot go outside because even just walking is to difficult on my heart.And another symptom is high ANA titer it is an autoimmune test. Symptoms *heat intolerance * POTS/Dysautonomia * High autoimmune blood markers(ANA)

Does anyone here who is diagnosed with MS have POTS?

Dear friend, to be honest I don’t know much of what you speak of when you refer to POTS/Dysautonomia. What I DO know is heat is MS’s worst enemy in that it makes your limbs feel like cement. Holding a book can be near impossible. In a nutshell, it makes you beyond weak. I was diagnosed one year ago. Even in winter I can become extremely heavy limbed. By all means get the MRI. In my case, I also had a spinal tap which conclusively diagnosed me. All the best to you.
