MS Infusions

My adult son is thinking about finding out more about infusions. We read about two ladies who had treatment outside of UK.
Is it available on NHS ? Is it expensive to pay for ? Can you request further information from your MS or consultant ? Is treatment available in England ? Sorry for all the questions, thanks for reading

If you mean HSCT, then it is possible to get NHS treatment in the UK, but the criteria is quite strict.
