People with medical conditions often travel abroad to receive treatment for their illness. Sometimes the treatment might not be available at home or the fees might be extortionate. Lengthy NHS waiting lists and worries about MRSA in UK hospitals have also encouraged British sufferers to seek treatment overseas.

As well as being a great place to enjoy the sun, sand and sea, Costa Rica is a hotspot for foreigners seeking surgery, dental work, cancer treatment, cosmetic surgery and stem cell treatment.

But a Costa Rican clinic has been criticised for the viability of their stem cell treatment - the health ministry believes that there is no proof that the procedure actually works or that it is indeed safe.

A doctor at the clinic admitted that the stem cell treatment hadn’t been approved, but former patients are outraged that others won’t be able to benefit from the treatment. Previous patients have nothing but praise for the stem cell treatment that they have received in Costa Rica.

Cranston Rodgers, who has benefited from stem cell treatment for his multiple sclerosis, said: "I think it’s ridiculous, in all honesty. I know what it did for me. I haven’t used a cane or a scooter since I used the first treatment."

Before taking the decision to receive medical treatment abroad, discuss the idea with your doctor. Once you have found a suitable facility abroad, research it thoroughly to ensure you are booking into a reputable clinic. If you will need to travel a long distance, your doctor will be able to tell you if you will be fit enough to travel. Ask a friend or family member to go with you for support and to lend a hand while you are recovering.
