Hi Kat 13;
I don't have an official diagnosis yet, but I can say that I also have terrible migraines, and do not tolerate light very well at times. I have been known to walk around indoors with sun glasses on. I don't know about the pain in the ear from noises, but I have read that people suffering with MS can have a variety of sensory issues. Most of the pain I get in my ears, I think is actually from my jaw problems. Walking is awkward for me and my legs feel pretty tired most of the time, but if I notice a big change in leg weakness, I always look into my iron levels because when I am iron deficiant, my legs feel like lead. The tingling I get in my legs are usually always in the same places (left foot, left knee, left thigh) and is not usually both legs or the whole leg but in very certain spots. Sometimes I will get a new spot, but once I have it, it remains. Memory problems and speech problems I have also read are common with MS. I know that my memory has declined drastically in the last few years, and as far as difficulties with speech, it feels more like I either cannot find words (easy words that I should know), or they want to come out backwards like a word salad comes out.
I'll be waiting for a response for you on your question because I am also new and very curious about many of the same questions you have above. These are good questions.
