[|Human|] Vascular Question: Hello, I had a bad case of diarrhea three weeks ago. I was in the bed for 1 week, just lying there because I had no energy. About 10 days after the diarrhea started, I was still very tired and still lying around. (I am usually up and about almost 14 of my 16 waking hours, run up the stairs, and am very active.) On the 10th day, I was talking on my cell phone for about 1 hour, when suddenly a saw a huge round ball form on my left arm (the one holding the phone), about the size of a small golf ball. I had not done anything to hit my arm, and had not been outside to get bitten by any bugs. While I watched over the next 5 minutes, the bulge on my arm proceeded to move toward my wrist, and form a bulge that was 5 inches long, 3 inches wide and about 1 inch high. I went to the pharmacy to purchase Benydryl, thinking it might be a bug bite, but the pharmacist told me to go to the emergency room. The doctor there said that it was a burst blood vessel, and it would form a bruise and go away. It did look like a lot of bruising over the next few days, but after two weeks now, the bulge is still there and is very tender. The bruising look has almost gone away. Perhaps my prolonged bed rest had something to do with it, or the extended time that I was using the cell phone. My GP has looked at it and said don t worry, it will go away, but I am concerned that I might have a blood clot that will travel out and cause a big problem! What do you think?
[|AI|]  Hi and welcome to Chat Doctor. Thank you for your query. In most cases this is just a swollen lymph node which doesn't require any specific treatment. Also, considering your description this may be some other benign subcutaneous lesion such as lipoma, fibrous or atheroma and if there are no skin changes such as redness, pus discharge or pain and fever then you should not be worried since it can be easily surgically removed under local anesthesia. Then it there is doubts it can be sent to the patohistologic analysis. I hope I have answered you query. If you have any further questions you can contact us in every time. Kindly regards. Wish you a good health.
