Welcome MM, nice to meet you.

If this is MS and you are anything like me, I had my first noticable MS symptoms at 23/24 and was not DXed until 36. Then just had slight symptoms until 53, reDXed and and now 72.

MS is not easy to DX. Your old Neuro sounds like a dingbat, however, so glad you have a new one. Try to be patient for your DX, because, if it's MS, it won't go completely away and with a knowledgable Neuro working with you a DX will come sooner, hopefully.

In the meantime, take a deep breath and live your life to the fullest, as able. Ask your Doc or Neuro to treat your troubling symptoms , such as pain, fatigue..etc..

Good wishes..
