About 1 month ago my left arm starting hurting all the way from the shoulder to the wrist. It stayed that way for a few days and hurt the most when I tried to extend it. Then it became numb from the inside wrist area to the inside elbow. I'm also having a "sunburn" feeling on the top of my arm and even my bicept. Then a few days ago I started to feel a very slight numbness in my right fingertips and some tingling in my right arm.
I've been researching a lot on the internet and I'm paranoid that it is something bad like ALS or a brain tumor. I went to an orthopedic doctor twice and he X-rayed it and my neck and sees nothing abnormal. Gave me a steroid pack and it had no effect. He has referred me to a neurologist but my appointment isn't until next week.
Also lately I feel like my top right lip is a little numb causing me to speak funny. This symptom really worries me since trouble speaking is a ALS symptom and I'm really not sure if my lip is numb or if it is psychological. My left arm seems a little better but still hurts when I extend it fully. Feels "tight".
I'm 39 years old and in great health otherwise.
