Steve, you can read my posts from teh beginnging, i was exactly in your position in Oct. 06. I had the clean reports / EMG's and still problmes, but now, everyeone around you (family /docs / friends) now starting to wonder with all the "normal" test....?
If you still feel what you feel, and it continues, you should push for antoher EMG, but you should wait at least 2 months before, as doing another one now, will yeild almost the same results. I don't know if your in a ALS Clinic, but i would shoot for an appt. there, and let them do thier EMG, it will be extensive.
In the meantime, we can see that yor anxious and concerned. I got on Wellbutrin 300 mg / day and they have made a wonderful differnece. The welllburtin allowed me to focus on living, rathar than dying. It make me live for today, enjoy today, plan for tomorrow, plan how ot combat ALS symptoms and still keep a happy mind.
If i had know what it would do for me 5 years ago, i would have gotten on it 5 years ago.
YOu may need to try a few, Wellbutrin was the best for me, but there are other such as: Zoloft, Lexapro, Paxil, Prozac, Effexor. I tried Lexapro (made me to emotional); Paxil (Couldn't get out of bed next day); Effexor (Felt like i was in outer space). Wellbutrin was the one for me, and it's worked like a charm.
There are not many side effects to Wellbutrin, but one of them are is increased libido. WE (My Wife & I) love that part. It's also helped our marriage get thur our rough times by keeped the afterhours busy and interesting.
Good Luck
Jamid
