Hi, I am still having problems with my esophagus, I still have the sensation of a foreign body when swallowing (for about a month now), especially when I lie on my side, it becomes more noticeable. The laryngologist and gastroenterologist don't see any problems. The muscles in my limbs are much less resilient and tire more quickly than usual. I also feel strange localized numbness/pulling/tightening of muscles in different parts of my body, particularly in my hands and feet.
I have just now received the results of my EMG, which I am attaching below.
(this is the translation of the document into English)
Electromyographic examination:
- Left Biceps:
- Duration: 9.5 ms
- Amplitude: 515 µV
- Area: 556 ms*µV
- Size Index (S.I.): 0.44
- Polyphasic potentials: 8.0%
- Left Extensor Digitorum Communis:
- Duration: 9.1 ms
- Amplitude: 410 µV
- Area: 431 ms*µV
- Size Index (S.I.): 0.29
- Polyphasic potentials: 11.5%
- Left Glossus:
- Duration: 7.4 ms
- Amplitude: 777 µV
- Area: 866 ms*µV
- Size Index (S.I.): 0.75
- Polyphasic potentials: 19.2%
- Left Tibialis Anterior:
- Duration: 8.4 ms
- Amplitude: 644 µV
- Area: 674 ms*µV
- Size Index (S.I.): 0.67
- Polyphasic potentials: 35.0%
- Left Vastus Lateralis:
- Duration: 10.2 ms
- Amplitude: 1416 µV
- Area: 1666 ms*µV
- Size Index (S.I.): 1.44
- Polyphasic potentials: 26.9%
- Effort recording from the biceps muscle of the left arm: Rich in amplitude, 1.5-2.5 mV. During slight effort, action potentials of motor units of medium amplitude, duration, and SI index were registered as normal. At rest, electrical silence.
- Effort recording from the extensor muscle of the left fingers: Rich in amplitude, 1-2 mV. During slight effort, action potentials of motor units of medium amplitude, duration, and SI index were registered as normal. At rest, electrical silence.
- Effort recording from the vastus lateralis muscle of the left thigh: Rich in amplitude, 2-3 mV. During slight effort, action potentials of motor units of medium amplitude, duration, and SI index were registered as normal, with no significantly increased amplitude. At rest, electrical silence.
- Effort recording from the anterior tibial muscle of the left leg: Rich in amplitude, 1-2.5 mV. During slight effort, action potentials of motor units of medium amplitude, normal duration, and a reduced SI index were registered. At rest, electrical silence.
- Effort recording from the muscle of the tongue on the left side: Rich in amplitude, 2-3 mV. During slight effort, action potentials of motor units of medium amplitude, duration, and SI index were within normal range. At rest, electrical silence.
Conclusion: In the EMG recording from the anterior tibial muscle of the left leg, there is a suspicion of minor myogenic damage, without any pathological activity. The EMG recording from the other examined muscles was within normal limits.
By the way, I also did the ischemic test, and it came out positive.
Ischemic test:
The ischemic test was performed by applying an elastic band to the left arm for 10 minutes, with additional hyperventilation in the last 2 minutes. In the second minute after releasing the pressure, multiple discharges lasting from 6 to 8 minutes occurred in the dorsal interosseous muscle and the left muscle.
Conclusion: Positive ischemic test, indicating neuromuscular junction hyperexcitability.
Questions:
1. Could my symptoms and the EMG results in any way indicate ALS?
2. Is it possible that I have bulbar ALS starting in muscles that were not tested during the EMG, and that's why it wasn't detected?
3. If it's not ALS, do you have any idea what disease could cause similar muscle symptoms that match mine?
