The sensation of tightness is common, and it is due to the filler material deep within the tight space between the bone and the muscle. This generally starts to fade over 2-5 days and is inconsequential.
The tenderness and aching are usually due to the minor trauma from the injection itself and it too settles after several days.
To reduce the discomfort, some painkillers can help. However, do ensure you do not have any drug allergies before taking them.
Of note, delayed bruising might be seen after a few days and is nothing to worry about either.
