<s>[INST] Hi Doc. Ive noticed this lump on my right Forearm(On Top not under) over toward thee left of my right arm & just an inch from my hand. I think it could be associated with either a enlarged vein or a pulled muscle. But I can clearly see the vein & when I bend my wrist backwards I notice it looks Bulging. Theres no actual Pain but I do feel weakness in my arm & a occasional Burning tingling feeling but it is very Slight. What do you think it is. I do masturbate from time to time, Infact I 1ST noticed this at a time where I had masturbated the night B4. I also TYPE on my computer a lot as well. Ive also been on Prescription Pills or would this part just be a coincidence. [/INST] Hi, Dear,Thanks for your query to Chat Doctor. Studied your query in full depth of its details. Reviewed it in context of your health concerns. Based On the facts, You seem to suffer from-Ganglion Cysts of the Right forearm, as they are on top of the wrist with little burning sometime. As these bulge out on extension of the wrist backwards/posteriorly, this confirms the Ganglion of the Wrist small joints/ or it could be a bursitis of the ventral wrist./ or could be bursitis with Carpel Tunnel causing Burning pain.USG/CT study of the wrist right would fix the diagnosis. Arthroscopic CT guided Excision/or laser ablation is the gold standard treatment of Gangions in this wrist region. Hope this reply would satisfy you and would help you to plan further treatment with your doctor there. Welcome any further query in this regard, which would be replied in next session. Good Day!!
