Stroke symptoms: Doctor shares the subtle 'heaviness' sign that could strike hours or days before

"Typically, early warning signs are associated with alterations in circulatory, inflammatory, or blood-pressure factors, all of which are considered stroke-related risk factors," the expert told GB News.

If you're noticing more frequent high blood pressure readings, that's worth paying attention to, as are unexplained tiredness or new weakness affecting just one side of your body.

Dr Joy also pointed to persistent tingling or a heavy feeling in your arms, face or legs as potential indicators.

When these sensations come on suddenly or keep happening, they might suggest nerve function problems from reduced blood flow.

"These signs alone do not signify a stroke but do warrant immediate medical evaluation," Dr Kezia declared.

Vision, balance and speech

Vision changes are widely considered crucial indicators of different health conditions, offering important clues about blood flow to your brain.

While blurred or double vision, or darkness in part of your visual field, can be temporary and easily brushed off, they could signal an impending stroke if they come on suddenly and severely.

Speech problems are also an important red flag, according to Dr Kezia Joy. You may find it challenging to articulate your thoughts clearly or struggle to comprehend what others are saying.

Balance issues that weren't there before could also indicate poor blood flow to the brain. When several of these symptoms happen together or without warning, it's particularly concerning.

Headaches, dizziness and numbness

Because headaches, dizziness and numbness happen for lots of reasons, timing and context matter enormously. Dr Joy explained that sudden onset symptoms, especially when they're much worse than usual, need urgent attention.

The combination of symptoms is particularly important. If you're experiencing weakness, confusion, slurred speech or vision changes together, that's more worrying as it suggests circulation problems or nerve damage.

Pay special attention if dizziness or numbness affects only one side of your body. A headache with facial weakness or being unable to lift one arm needs immediate medical help.

Even if symptoms disappear quickly, getting checked early means doctors can identify potential causes before an emergency happens.

When should you call for help?

Dr Joy stressed that certain symptoms need immediate medical attention, even if they seem to improve.
