It seems like you are very focused on treating the pain which is completely normal but I can not stress enough the importance of finding out what exactly you are dealing with.

IF you have a serious vascular and arterial issue like I did, you need to have surgery. You can get blood clots and once that vein clots, there is a whole new level of damage on top of the damage caused by lack of blood and nerve irritation.

I highly recommend that you get the proper testing and figure out all this before continuing with pain management. You need to treat the cause, not cover it up.

I also wanted to add that it sounds like you do have a lot issues with blood flow. Since I had the surgeries my hands never swell anymore, they are always warm and they have color. Hope this helps
