Welcome to ThisIsMS,Esh. You have found an understanding group who generally try to help each other. Although we have all gravitated to this website, we are still unique individuals with unique experiences and unique ideas on the cause and way to treat this hateful disease of MS.
Since my own obsession focuses on insulin as a possible MS cause and you describe yourself as "overweight," I wonder if your physician has ever checked your fasting blood insulin level? A person cannot put on weight without insulin. Too much weight can indicate too much insulin.
Since you asked:
Could this be MS and if so, will it cause problems if I delay seeking care?
I offer you my opinion – it COULD be MS, but it could be many, many other conditions. You and your doctor will have to eliminate the possibilities; if MS is "the last man standing", then…
If by "care" you mean medications, I do not believe that a delay would cause problems. I encourage you to adopt a healthy diet (such as http://www.TerryWahls.org
) and exercise program without delay; in my opinion, diet and exercise have the greatest chance of a positive effect on MS – in the event this is your eventual diagnosis. In any event, a healthy lifestyle is good for everyone.
