Call 999
Call 999 for chest pain that feels tight or squeezing or spreads to your arms, neck or jaw, severe difficulty breathing, or collapse. Call 999 too if difficulty breathing comes on suddenly, or you have pain in your chest or upper back: these can be signs of a blood clot in the lungs (a pulmonary embolism). Don't drive yourself to A&E (accident and emergency).
The NHS also says call 999 or go to A&E for possible sepsis, if someone is breathing very fast; is confused, has slurred speech or isn't making sense; has blue, pale or blotchy skin; has a very high or very low temperature, feels hot or cold to the touch, or is shivery; or has a rash that doesn't fade when you press it.

During treatment: contact your hospital team straight away
Use the 24-hour number you were given, or NHS 111 if you can't reach them, if during treatment you have:
- A temperature over 37.5°C or below 36°C, or you suddenly feel unwell even with a normal temperature.
- Signs of infection, such as feeling shivery, a sore throat, a cough, diarrhoea, or needing to pee a lot or pain when peeing.
- Throbbing or cramping pain, swelling and warmth in a leg or arm, or coughing up blood, which can be signs of a blood clot. Sudden breathlessness or chest pain means 999 (see above).

Spinal cord compression: get advice immediately
Spinal cord compression is when cancer presses on the spinal cord. Contact your hospital team straight away, even at the weekend, and go to A&E if you can't reach anyone, if you have any of these:
- Back or neck pain that is new, severe or getting worse, worse when you move, cough or strain, or that disturbs your sleep.
- Problems controlling your bladder or bowel.
- Unsteadiness, difficulty walking, leg weakness or your legs giving way.
- Weak arms or hands, or trouble gripping.
- Numbness or pins and needles that is new or quickly getting worse.

Swelling, clots and infection
Signs of infection (cellulitis) or a blood clot in a swollen limb need urgent medical attention. If the swollen or at-risk area changes during or after exercise, stop and contact your lymphoedema specialist.
Same day (urgent GP appointment or NHS 111): throbbing pain in one leg (rarely both), usually the calf or thigh; swelling in one leg (rarely both); red, blue or darkened skin around the painful area, which may be harder to see on brown or black skin; or swollen veins. This can be a deep vein thrombosis (DVT). It is more likely after surgery, a hospital stay, 3 or more days in bed, a journey of over 4 hours, pregnancy or a recent birth, cancer, a previous clot, or contraception or hormone replacement therapy (HRT) that contains oestrogen.
Call 999 or go to A&E if breathing suddenly becomes difficult, if pain in your chest or upper back comes on suddenly with breathlessness or a very fast heartbeat, or if someone passes out.
Skin that is painful, hot and swollen can be cellulitis: ask for an urgent GP appointment or get help from NHS 111. Call 999 or go to A&E if you also have a very high temperature or feel hot, cold or shivery, have a fast heartbeat or fast breathing, feel dizzy, faint or confused, or have purple patches on your skin.
New swelling with no signs of a clot or infection: see your GP or cancer team, who may refer you to a lymphoedema service.

A fall with a knock to the head

Stop the session if
You feel any pain or become unwell, as the NHS advises for its Pilates videos, and especially for chest pain or pressure, unusual breathlessness, dizziness or fainting. If you have a health problem, an injury or any symptoms, get advice from a healthcare professional, such as a GP, before you start.

- Unusual back or bone pain, or unusual muscle pain.
- A headache that doesn't go away.

What's normal
Some soreness or stiffness for 2 to 3 days after exercise, and tiredness during it, is common. If you feel very sore or very tired, do a bit less next time.
