Man suffers severe spontaneous goosebumps and hypersensitivity despite normal medical tests.

Reader Andy McCormack from Manchester writes to describe a distressing condition he has endured for the past year: spontaneous, widespread goosebumps that begin at the head and race down the back, chest, and legs. The episodes occur randomly, even while he is simply sitting and reading. The skin has become so hypersensitive that the friction of a drying towel is intolerable. Extensive medical checks, including blood work, hormone panels, and heart monitoring, have all returned normal results.

Dr. Martin Scurr addresses this unusual and vexing complaint, identifying the extreme discomfort triggered by light touch as cutaneous allodynia. This condition arises when skin nerves become hypersensitive to stimulation. To provide context, Dr. Scurr explains that normal goosebumps are caused by the contraction of tiny arrector pili muscles at the base of hair follicles in response to cold or strong emotions like fear. This reflex, known as the pilomotor reflex, is an evolutionary remnant designed to trap air for warmth and make an individual appear larger when threatened.

Regarding the reader's specific symptoms, Dr. Scurr notes that such nerve sensitivity is linked to several common conditions, including shingles, diabetes, and migraines, all of which are nerve-related. More rarely, it could indicate temporal lobe epilepsy, a condition affecting the side of the brain that can sometimes trigger pilomotor seizures or spontaneous goosebumps. He advises the reader to consult their GP for a referral to a neurologist. If epilepsy is the cause, suitable anticonvulsant medication should hopefully eliminate these unpleasant sensations. Dr. Scurr expresses optimism for a resolution.

In a separate query, Margaret Baker from Grangemouth reports taking 10mg of omeprazole for at least 25 years to manage a hiatus hernia. She has read concerning stories about the drug and considered stopping, but found her hernia became sore without it. She is also concerned about newly developed arthritis and wonders if the medication is linked.

Dr. Scurr responds by noting that omeprazole is a proton pump inhibitor (PPI) widely prescribed to suppress stomach acid production, a fact that underscores its general safety profile and the reason it is often available without a prescription. He emphasizes that any long-term medication requires annual reassessment to ensure benefits outweigh risks. Since the drug effectively eases the pain of her hernia, the benefit of her modest dose is clear and must be weighed against potential harms. He highlights that because stomach acid is necessary for absorbing vitamin B12 from food, long-term PPI use carries a risk of deficiency, which can lead to fatigue and muscle weakness. Similarly, prolonged use can affect the absorption of magnesium and calcium. A lack of calcium may result in weak bones and increased fracture risk, while a magnesium deficiency can cause muscle cramps and heart rhythm problems.

Annual blood tests are now required to monitor these specific levels.

Suppressing stomach acid theoretically increases the risk of infection from organisms entering the gastrointestinal tract, such as C. diff or Salmonella, both of which can cause severe diarrhea, fever, and pain.

The serious risks associated with long-term use, including weakened bones, are not definitive, especially since many patients on these highly effective drugs for extended periods also suffer from other health conditions requiring different medications, which may introduce interactions.

There is no evidence linking the long-term use of omeprazole to arthritis.

It is advised to continue taking the small daily dose of omeprazole while discussing concerns with a doctor on an annual basis.
