My Hand, Forearm And Calf Seem To Be Experiencing “weakness”.

Question: My hand, forearm and calf seem to be experiencing “weakness”. I can do all tests normally, run and lift. I can zip zipper and open bottle tops and am only occasionally clumsy. My thumb pad gives some resistance when I circle my thumb around in circles and my forearm burns and feels fatigued very very quickly. I can stand on my toes and walk on my heels but the right calf just fatigues faster. I have no cramping and while I do have twitches they aren’t too noticeable or out of control. It follows exercise. My knee sometimes hyper extends while running on that side. The feeling is more of fatigue. I’ve experienced this now for exactly 30 days. Could this be a sign or als/ms or other mnd? It’s been occupying my thoughts a lot. I have not yet had an emg - should I?

Can als begin in a forearm or wrist? If it did it would be painless correct and I would be unable to do tasks? As it stands, I can summon the strength to do anything. It just fatigues faster on my right side.

I have seen a neurologist and passed all of the reflex tests and she didn’t seem concerned although she offered an emg. But my symptoms have gotten I think worse. Perhaps from anxiety. I regularly rest my fingers and arm strength which may lead to the fatigue, but I test both sides. My leg though, seems like a different issue. I am in full control of it... it doesn’t buckle and I don’t have spasticity. I do not have blurred vision, heat intolerance, numbing or anything like that. Would that point to vascular? I have been having a hard time letting als go since it was planted in my brain but it’s true, when push comes to shove I do not have clinical weakness. Just fatigue but I can still do all activities symmetrically. The symptoms are specifically confined to around my knee and calf/shin forearm and wrist. My fingers are sore and strained I think from me messing with them.

If you believe this is not ALS or another mnd - do you think these symptoms seem urgent or indicative of something fatal/degenerative?

Do you feel this has progressed to quickly (30 days) to be als?

Both a pcp and neuro have both told me not to worry about it - If both of them, and yourself say that, I should let als totally go right?

I am fit, never been in a car accident, never had prior history. Not sure where this would have come from out of the blue. But I have a son, so naturally I’m concerned. Thanks!
