I am a Consultant Rheumatologist & Physician at Bedfordshire Hospitals NHS Foundation Trust having
completed my Rheumatology & Internal Medicine speciality training in the East of England in 2013.
I undertook my junior doctor training in Swansea. Having obtained membership of Royal College of
Physicians London (MRCP) in March 2007, I commenced higher specialist training in Rheumatology & General
Medicine before joining Addenbrooke’s Hospital Cambridge to pursue clinical research in 2010. Same year, I
achieved MRCP in Rheumatology too. I finished research in 2012 and joined Luton & Dunstable University
Hospital as a final year registrar until was appointed in the current role. I was awarded Fellowship of
Royal College of Physicians London in 2018 and appointed as Director of Research & Development in 2019. I
was also elected to the prestigious Registers committee of national British Society of Rheumatology in
2019.
I am the lead clinician for award winning early arthritis service, research on biologic
therapies and inflammatory arthritis associated lung diseases MDT service. I have been
involved in more than 80 clinical trials utilising biological therapies for autoimmune
conditions. My other main interests include early inflammatory arthritis including
ultrasound use and metabolic bone health. I have authored over 180 abstracts, presented at
international conferences and published more than 70 papers in peer reviewed journals.
If you have painful joints, stiffness and/or joint swelling then you could have any one of 207 types of arthritis. I lead a national award winning early arthritis service
If you have any of the predisposing conditions such as psoriasis, uveitis/iritis, inflammatory bowel disease and you develop joint pain, it could be spondyloarthropathy. I lead on research in such conditions
If you are over 50 or younger with high risk factors such as chronic disease, steroid use or hormonal disorder, you will need bone health screening. I lead innovative metabolic bone health service
If you have longstanding back or muscle pain and there is diagnostic uncertainty, I can help you reach a diagnosis and formulate a management plan
If you have multisystem complaints e.g. rashes, ulcers, breathing problems with joint/muscle pain, it could be connective tissue disease. I lead a multi-disciplinary service and can help you
Excellent diagnosis and advice. Really speeded up my referral and immediately helped with pain relief

Jan. 21, 2026, 6:07 p.m.I was given a bisphosponate infusion at Bedford hospital and almost immediately suffered side effects. Despite trying to register my symptoms and concerns with healthcare professionals -I was told on numerous occasions that this couldn’t be correct -at the end of my tether I requested a private appointment and saw Dr Nissar. He very quickly identified risk factors, differential diagnoses and required investigations He was very knowledgeable, polite and empathetic (something sadly missing in my encounters with staff within the NHS) He explained clearly the differential diagnoses and next steps. I felt heard which was an enormous relief.

It was refreshing to feel heard and given a potential diagnosis at my first appointment
