Yes, I had one. I had to have it removed due to the fact it was about to travel to my heart from what the doctor's said. It started out as a small bump, then became larger and larger. It then became painful and started to enlarge my vein and turn purple on my arm. I rushed myself to the hospital because of the pain. It felt like my thumb was going to explode. I spent 3 days in the hospital. Take it seriously and have it checked out.
I had a clot in my thumb about 15 years ago. My thumb started to shrivel and it took them 6 weeks to figure out why. To diagnose they ran several tests, but by putting little blood pressure cups on my fingers they found the problem. It was a clot. I was put on aspirin therapy. They checked again after a couple of weeks and the clot was gone. I took aspirin for 15 years until I developed a DVT in my calf. Now I get to take coumadin for that.
Yes you can.but it isn't nothing like the clots that you can get in your legs.or other parts of your body.. Take care..
