Hi there. Thank you for your question. I will be helping you out with your queries
Is there any swelling of the joints?
For how long does the pain and morning stiffness last?
Are the joints of your hands also involved?
Do you have pain in any other parts of the body?
Please let me know.
No swelling - stiffness lasts all day and increases if I've been sitting down
Are joint movements painful especially in the morning?
The first thing that comes to mind with the symptoms that you are having is arthritis.
Polymyalgia is a less likely possibility.
The reason why I say that is because polymyalgia affects the proximal muscle groups i.e. the arms and the hips more than the distal parts.
However, I would like that you should be seen and investigated further to get to the bottom of this.
You should book an appointment with your GP ASAP.
