Hi. Whilst playing tennis 4 weeks ago I got a very severe pain in my forearm half way between wrist and elbow on the Alna side. The pain quickly subsided after about 3 mins, and I carried on playing to finish match. Next morning my arm and hand had swelled and ached like mad. Put ice on it and took a ibuafren pill. Went to doctors, they suspected a slight fracture or crack but X-ray didn t show anything. Been resting now for 4 weeks. All seems well except a weak feeling and this small bump the size of a small pea that remains in the said area of the forearm. This bump only hurts when touched. Any ideas? Am I safe to play tennis/gym etc??
