Brain issues (hypoxia, dizziness)
Two weeks ago, while working out (performing incline bench press with a barbell), I struggled to lift the barbell on the last rep due to near exhaustion.
Immediately after, I felt tightness around my forehead extending to the back of my head, followed by dizziness.
I initially thought it was a Valsalva maneuver, so I went home to rest.
Now, it seems there are no major issues, so I've started light exercise again, but I still experience tightness in the back of my neck and head, along with dizziness and a feeling of hypoxia after exertion.
However, during aerobic exercise, even at a higher intensity, I do not experience these symptoms (based on heart rate as a measure).
I would like to ask the doctor if this could be related to an issue with the cerebral blood vessels, or if it might be an injury to the cervical spine, or if it is simply a sports injury that requires rest?

Hello Mr.
L: You mentioned that "there is a tightness around the forehead extending to the back of the head...
and I have been experiencing tightness in the back of the neck and dizziness due to exertion and hypoxia." It may be necessary to first consider issues related to the cervical spine or cervical myofascial structures.
Cervical myofascial pain syndrome typically presents with pain at the affected site, discomfort, muscle stiffness, or a heavy pressure sensation, and sometimes palpable myofascial trigger points can be felt under the skin.
Symptoms often worsen upon waking or with changes in weather, but can be alleviated with stretching activities, and they frequently recur.
During acute episodes, there may be local muscle tension, spasms, and limited mobility.
Regarding your mention of "cerebral vascular disease," it is common for local ischemia to occur after hyperventilation, which can lead to symptoms resembling seizures or local neurological dysfunction due to cerebral ischemia.
I recommend consulting with a rehabilitation specialist or a neurologist for further evaluation and treatment.
Thank you for your inquiry, and feel free to discuss any related questions! Wishing you good health, peace, and joy.
Dr.

More Info
Dizziness and neck tension after weightlifting can be concerning symptoms, particularly when they persist beyond the immediate post-exercise period. Based on your description, it seems that you experienced a significant strain during your workout, which may have led to a few potential issues that could be contributing to your ongoing symptoms.
Firstly, the tightness you feel around your forehead and the back of your head, combined with dizziness, could be indicative of a tension-type headache or a cervicogenic headache. These types of headaches often arise from muscle tension in the neck and shoulders, which can be exacerbated by strenuous activities like weightlifting. The act of lifting heavy weights can lead to muscle strain, particularly if proper form is not maintained or if the weights are too heavy for your current strength level. This muscle strain can cause referred pain and tension that radiates to the head, resulting in discomfort and dizziness.
Moreover, the dizziness you experienced could also be related to a phenomenon known as "exercise-induced dizziness," which can occur due to a variety of factors, including dehydration, inadequate oxygen supply to the brain, or even a sudden drop in blood pressure after exertion. When lifting weights, especially near fatigue, your body may not be able to maintain optimal blood flow, leading to sensations of lightheadedness or dizziness. This is often temporary and resolves with rest and proper hydration.
Another consideration is the possibility of cervical spine issues. If there was any awkward positioning of your neck during the lift, or if you have pre-existing cervical spine conditions, this could lead to nerve compression or irritation, which might manifest as neck tension and dizziness. Conditions such as cervical radiculopathy or even a herniated disc can cause similar symptoms, particularly if there is pressure on the nerves that supply the head and neck.
It's also worth noting that the fact that you do not experience dizziness during aerobic exercise, even at higher intensities, suggests that your cardiovascular system is functioning adequately during those activities. This could imply that the issue may be more musculoskeletal in nature rather than a systemic cardiovascular problem.
To address your symptoms, consider the following recommendations:
1. Rest and Recovery: Allow your body time to recover from the strain. Avoid heavy lifting until the symptoms resolve.
2. Hydration: Ensure you are well-hydrated before, during, and after your workouts. Dehydration can exacerbate dizziness.
3. Gentle Stretching and Strengthening: Engage in gentle neck stretches and strengthening exercises to alleviate tension and improve muscle balance. Physical therapy may be beneficial if symptoms persist.
4. Proper Form: When returning to weightlifting, focus on maintaining proper form and consider reducing the weight to prevent further strain.
5. Consult a Specialist: If symptoms persist or worsen, it would be prudent to consult a healthcare professional, such as a neurologist or a physical therapist, who can conduct a thorough evaluation. They may recommend imaging studies like an MRI or CT scan if there is concern about structural issues in the cervical spine.
In summary, while your symptoms may be related to muscle tension and strain from weightlifting, it is essential to monitor them closely. If you experience any new or worsening symptoms, such as severe headaches, persistent dizziness, or neurological deficits (like weakness or numbness), seek medical attention promptly. Early intervention can help prevent more serious complications and facilitate a quicker recovery.
