For years I’ve suffered with swollen, itchy lips when I go out in the sun. I’ve tried putting factor 50 suncream on but it doesn’t help. Do you think it could be an allergic reaction?
Dr Ellie Cannon replies: While uncommon, it is possible for people to be allergic to the sun. This condition – known as solar urticaria – can cause a rash, normally on all sun-exposed parts of the skin.
However, it is possible that some patients, who have a mild case of solar urticaria, are only affected on their lips, as this skin is more sensitive.
Trying a daily allergy tablet, called an antihistamine, would be a low-risk option.

These are generally very safe and available over the counter. There is also the added benefit that, if you take the pill and the irritation goes away, then you can conclude that the cause is an allergic reaction. A good one to try would be fexofenadine.
Another reason why the lips may be irritated is a reaction to the heat – hence why suncream doesn’t help. In fact, it is possible it may even be a reaction the suncream itself, which is known to trigger the itchy skin condition dermatitis.
The best cream to calm down irritated lips is petroleum jelly – such as Vaseline – or a beeswax-based lip balm. If these don’t work, then a steroid cream may help. However, this would need to be prescribed by a GP.
During a check-up I gave a urine sample which turned out to contain traces of blood. The GP asked questions about my bladder habits – I said I do need to go all the time – and booked me an appointment with a specialist in October. Should I be concerned?
Dr Ellie replies: Blood in the urine is something that we always take seriously.
If the blood is visible – the urine is pink, red or dark brown – it can be a sign of bladder cancer, so a referral to see a specialist within two weeks should take place.
However, if there are only traces of blood – which cannot be seen but are picked up in a urine test – this is less likely to be cancer.
Other causes of blood in the urine include a urinary tract infection. This would usually be accompanied with a burning sensation during urination, a high temperature, cloudy pee or lower back pain.
Kidney stones can also lead to blood in the urine. Again, this would likely have other symptoms, including pain in the sides, back or groin as well as nausea.
In order to find out the cause, a specialist may carry out a more invasive investigation, including a cystoscopy, which is a thin, flexible camera that is inserted into the bladder via the penis.
Another trigger of blood in the urine is an enlarged prostate, a common condition in men over 50, which makes it difficult to pee or leads to a sensation of needing to pee suddenly and often.
If this is the cause, treatment would include drugs that shrink the prostate and, if necessary, surgery to remove excess tissue.
Whatever the cause, a urologist should be able to help you with your overactive bladder.
There are medicines which can help reduce the urge to pee, as well as nerve treatments, which use electrical currents, which have the same effect.
I was diagnosed with arthritis in my hands and I’ve been told to take 600mg of ibuprofen up to three times a day. My doctor also suggested rubbing ibuprofen gel into the joints. Do you think this is an unsafe amount of the drug to take?
Dr Ellie replies: The usual recommended dose of ibuprofen is 400mg taken three times a day. Consuming more may be dangerous.
The anti-inflammatory drug is effective at reducing joint pain and stiffness. In some cases, such as dental pain, menstrual cramps or arthritis, doctors may prescribe a 600mg dose that can be taken four times a day.
However, it is important that patients do not combine the maximum dose of tablets with ibuprofen gel, as this can raise the risk of side effects. Too much ibuprofen can irritate the stomach, leading to nausea and vomiting. In large amounts this can also trigger painful stomach ulcers.
Taking high doses over long periods can also increase the risk of stroke and heart attack.
If ibuprofen does not help, there are other options. The painkiller paracetamol can safely be taken alongside it, while many find that creams which either heat up or cool down the hands – such as Deep Heat – have a positive effect.
Some patients also benefit from hand physiotherapy, which helps to reduce stiffness through exercises and stretches. Finally there are prescription anti-inflammatory tablets, which tend to be more effective than ibuprofen, such as etoricoxib and celecoxib. However, they would need to be discussed with a rheumatologist, as they carry a number of risks, including raising the risk of heart disease and strokes.
