Hi, Thanks for using HCM.
The swelling you are refering may be beingn or can be malignant one.
If there is no weight loss
, sudden increase in size, change in consistency, structure, colour of skin, inflamatory changes then probably benign condition. Since on tapping it or pressure on it gives shooting pain this may be ganglion
or swelling affecting the nerve
. I advice you to take an Xray to see where its origin and also the surrounding structure if affected. Later on we can go for management based on different investigation reports and its diagnosis by your doctor.
Hope I answered your question. Feel free to ask me if you have any further queries. Wish you good health. Take care.
