Are these symptoms related to my MS?

Question:
I'm a 50 year old female who was diagnosed with RRMS 10 years ago. I'm finding that as I age I have symptoms pop up and at times it is confusing as to what symptoms may be related to my MS vs. something completely different and unrelated. Two new issues have me wondering which of my providers I should be seeking treatment from. 

1.) The past few months I've noticed that if I am on my feet too long my right leg will go numb/tingly. Considering this only happens when I'm on my feet would this most likely be due to a back/sciatica issue vs. my MS? 

2.) My right ear has become very painful when I yawn. At no other times does it bother me. My PCP has looked at it and isn't finding anything wrong with the ear itself and suggested if it continues to see treatment from ENT. Could it be possible that the ear issue would be related to my MS? I'd hate to start seeing another provider if there is a possibility that it is just the MS. Thank you so much for your thoughts/suggestions. 

Answer:
You are right. As we age there are more potential problems to consider as a cause of our underlying problems. A good MS specialist should be able to determine if your symptoms are related to MS or should be addressed by another specialist. In your situation both symptoms could potentially be related to MS; consideration of your history, additional questions and an examination will help your MS specialist make a determination
