Read straightforward guidance on calf cramps, stopping metformin after remission, and recognizing and treating torticollis
The following answers bring together likely causes, simple checks and treatment paths for three problems readers often ask about: painful night-time leg cramps, the dilemma of stopping metformin after weight-loss treatment, and a decade-long tightness on one side of the neck.
Each topic below explains what is typical, what to test for, and conservative measures you can try at home or discuss with your GP. Throughout I flag when specialist care or investigations may be appropriate.
Night calf cramps: what they feel like and why they happen
Many people experience a sudden, intense pain in the calf when the muscle contracts without control. The sensation is caused by an involuntary contraction of the muscle and can last from seconds to several minutes; an ache or tightness often lingers.
Common contributors include dehydration, temporary muscle fatigue after unusual activity or long walks, and electrolyte imbalances. Nutritional factors such as low levels of B vitamins or vitamin D have also been linked to cramps in some patients. Foods rich in B vitamins include whole grains, meat, eggs and leafy greens; vitamin D is mainly obtained from sunlight and oily fish.
Tests and treatments for persistent cramps
A GP can check for deficiencies with simple blood tests to measure B12, other B vitamins and vitamin D. If a deficiency is found, correcting it with diet changes or supplements often reduces symptoms. Some people report benefit from magnesium supplements, though evidence varies. For severe, disabling cramps, doctors sometimes consider quinine tablets; however, these carry potential risks, including cardiac side effects, so they are reserved for serious cases and monitored closely. On rare occasions, recurrent cramps may be an early sign of neurological disorders, but such diseases usually present with other progressive symptoms like weakness, stiffness or spasms, so a long, stable history without worsening makes a serious neurological diagnosis unlikely.
Should you stop metformin after diabetes remission?
Metformin is prescribed to lower high blood glucose and reduce the risk of diabetes complications such as heart disease and organ damage. When blood sugar returns to a healthy range and diabetes enters remission, the direct benefit of continuing metformin becomes minimal. Recent social-media claims suggest wide-ranging anti-ageing or cancer-prevention effects for metformin, but robust evidence for such benefits in people with normal glucose control is lacking. There are also downsides: long-term metformin can cause gastrointestinal symptoms and contribute to vitamin B12 deficiency, which affects nerve and brain function.
Mounjaro, Wegovy and the question of relapse
Drugs developed for diabetes that also produce weight loss, such as Mounjaro and Wegovy, act to reduce appetite and lower blood glucose. Their appetite-suppressing effect generally persists only while the medication is taken; many people regain weight and see blood sugar rise again after stopping. These treatments are often privately funded and long-term use may be expensive. Before discontinuing a weight-loss medication, it is sensible to implement sustainable lifestyle strategies—limiting refined carbohydrates and sugary drinks, prioritizing regular moderate exercise, and monitoring blood glucose—so that stopping medication does not immediately reverse the metabolic gains.
Long-term one-sided neck tightness: torticollis and other causes
Chronic tightness on one side of the neck that pulls the head position, causes a raised shoulder and sometimes a clicking sensation can reflect a form of torticollis, also called cervical dystonia in neurological terminology. This condition involves involuntary contraction of neck muscles and often produces a dull, persistent ache. More commonly, an old muscle injury, repetitive strain or years of poor posture is responsible rather than a progressive neurological disease. Associated symptoms such as arm weakness or widespread neurological decline would prompt further investigation.
Physiotherapy and conservative care
The first-line approach is usually physiotherapy, with programs that stretch tight muscles, strengthen opposing muscle groups and correct posture. Targeted exercises can reduce the degree of contraction and the frequency of clicking or pain. GPs may recommend short courses of painkillers or muscle relaxants while rehabilitation is under way. Small, consistent changes to workstation setup and sleeping posture can also make a big difference.
When to see a specialist
If symptoms remain severe despite conservative measures, referral for specialist treatment is appropriate. In selected cases, injections of botulinum toxin (Botox) into overactive muscles can reduce abnormal contraction and improve posture. Imaging such as X-rays or MRI may be advised if there is concern about structural problems or if symptoms follow an injury such as whiplash. Progressive or rapidly worsening signs would warrant prompt neurological assessment, though this is uncommon.
Other findings: alcohol, coughs and how to contact me
Recent research has reported that some people taking weight-loss injections see a substantial reduction in alcohol intake, prompting interest in whether these drugs could help treat alcohol use disorders. If you have noticed a change in drinking after starting injections such as Mounjaro or Wegovy, I invite you to share your experience. Separately, persistent coughs that do not resolve could in some cases be due to whooping cough (pertussis), which is rising in adults and can present without the classic childlike “whoop.” If you have an unexplained prolonged cough, discuss testing with your GP.
