Hello Dr. I m not sure why you are here but thank you. I was out for the evening having a few cocktails (4) and had cigarettes (4) with a friend who left and a stranger engaged me in a conversation and noticed I had a hard bump protruding on the left inner side of my left wrist (as you look at your own wrist), 1/2 size of a grape. I had not noticed it before and did not feel it. This has never happened before. Events today: -Hair cut/first time razor shave -Pedi and Manicure -Stopped at CVS to check my blood pressure 2pm EST (just over normal) / hidrated -Took my normal meds today (2 high blood pressure in the morning) -Just check my blood pressure just now and it is normal -Before I went out 5 hours ago I took a 20mg sildenafil Have been applying cold incase it is some kind of inflammation but things I ve quickly read suggest cysts that should have hot. -Have been under tremendous stress lately -Not sure if I should go to an ER or wait until morning to go to Urgent Care

Hello, Thanks for trusting Chat Doctor ! I have gone through your, and I can understand your concerns. As per your description it seems that you have a minor condition called ganglion cyst. You don't need to worry regarding this because it is a harmless condition and highly effective treatment is available. It is benign(non-cancerous) swelling and no treatment required is required unless you have pain, or it causes cosmetic problem. I suggest you to consult an orthopedic and get evaluated to make a diagnosis. Treatment is by surgical aspiration or by surgical excision. Hope I have answered your query. Wishing you good health. Regards. Chat Doctor.
