Hello from JustAnswer.
Have you had any evaluation for the tingling and numbness?
Are you having any other symptoms of the legs or lower back?
Thank you for the additional information.
While there are some interventions that can be tried without seeking further evaluation of the underlying cause of the tingling and numbness, it is better to pursue an appropriate evaluation when there are persistent symptoms.
There are a couple of interventions that can be done at home that may be able to help. Some people can get tingling, numbness, or burning because of musculoskeletal inflammation that is pressing on a nerve. Using an anti-inflammatory medicine, such as ibuprofen or naproxen, can ease inflammation and relieve the pressure on the nerve in these cases.
There also is an over the counter cream that can help directly ease tingling or burning, so may help for a variety of underlying causes. The cream is called capsaicin, and it is available in a number of brand names. When the cream is first applied, it may make the tingling worse, but as the medicine accumulates in the system over a couple weeks, it will typically help ease the tingling and burning.
It also may help to take a multi-vitamin supplement, particularly the B vitamins.
If I can provide any additional information, please let me know.
The other thing that you can take is the capsaicin cream that I noted above. There are many different brand names that are available and it varies by country. The system says that you are from the UK, and one of the brand names that I can find that is available in the UK is Nature Knows Best Chilli Muscle Rub.
