"10 weeks later we are no nearer to a diagnosis"

My husband has waited now nearly 6 weeks for x-ray results and they still are not back even following a 4 week wait initially for an appointment. Our GP assures that these have been chased and we were advised that originally it would be 7-10 days for the results and now 10 weeks later we are no nearer to a diagnosis and my husband struggles to get out of bed every day with the pain. Due to a long term condition he cannot take regular painkillers and therefore having to rely just on paracetemol whilst its diagnosed is compounding the issues. I feel the NHS is great in many ways but also lets down so many and over the past few years, this is just one example.
