Thanks for the query at DoctorSpring.
Temporal arteritis is unlikely in your cases , especially since you are <50 yrs of age. I feel your symptoms are more likely to be vascular headache. You can take a OTC pain medication like Ibuprofen twice daily and see whether it aborts your headache.
If there are any eye symptoms or persistent pain you need further evaluation. To rule out temporal arteritis for sure you need to alteast get a ESR and CRP done (both blood tests easily available).
There are specific investigation like USG and doppler study of temporal artery, but those are not required at this stage. For now if the pain persists please get ESR and CRP done. If there are eye symptoms get medical help without delay. Please do update me with the reports.
Feel free to ask followups
Patient replied :
Thanks for the reply, though sorry if I didn't make it clear - I have no headache at all. Just pain on and all along the swollen vein when touching it.
When would make this one vein inflamed?
Asprin does not remove the pain. I had some bloods taken a few weeks ago for my nightsweats, I will see if I can get the results.
Sorry I missed that point - Absence of headache makes Temporal arteritis even less likely. That means there is no emergency. The swollen artery could be due to a local arteritis (infection / unnoticed trauma / rarely immune mediated) . It will be better if you can confirm the vein swelling from a Doctor ie, whether it is a vein or temporal artery which is swollen. Veins can swell up for a number of reasons and most of them are non specific and non significant. On the other hand artery swelling is rare.
In view of the night sweats it is better to get a baseline tests done. Do share with me the reports you have (if possible). I will suggest other tests if needed.
Do note that the aim here is not to get a diagnosis, rather than rule out any significant disease at first.
Hope this helps
