I also have a vein that is swollen and that gets bigger at times and very painful to the touch. Could there be a cyst under the vein or an aneurysm? It is on my lefthand index finger between the knuckle and first joint. I am a 65-year-old woman and did not injure the site.
Hi,
Thanks for query,
You have not mentioned your age, if you are elderly there is chances of having inflammation of the bone in the nerve route causing pain in the fingers. There is possibility of some pressure on brachial plexus while sleeping pressure giving rise to nerve route
pain.
Hope this answers your query.
Take care
