Here's a bit about me; I'm 18 years old, I'll hopefully be going to university in September. I'm really not the healthiest of girls, I almost never exersise; I do sometimes play the Wii with my friends and I'm a part-time waitress so I run around for an hour in a shift, I'm just really lazy otherwise. (in case you think any of that is relevant)

Every now and then I get unbearable pain in my left wrist along the vein from my forearm to the base of my hand, it doesn't hurt much on my arm but on my wrist (where you can see the veins) it's extremely painful. Usually I either squeeze it tightly for a long time, hit/slap it repeatedly or push my knuckles from my elbow to the base of my hand over and over for it to go away.
I don't know if it's relevant but I also get a shap throbbing pain on my upper arm where I had my TB jab six years ago, and in my back and legs, it isn't as painful and doesn't last as long, in fact I hardly notice them really so I'm not too concerned, but my wrist is excruciating to the point of near tears.

You need to see a doctor right away.. You may have Carpel Tunnel Syndrome or Ulna Wrist Syndrome.There is inflammation somewhere.If you can't see a doctor right away go to the pharmacy and get some Ibuprofen... the strongest you can find.I have been through this and still am going through this.Hope you feel better soon :)
