Thank you for contacting ask the doctor.
No a bump after 5 months is not normal. this could be an abscess or a wound infection. in either case It definitely needs looking at. I recommend a visit to the physician to get a complete check up. abscess is a collection of pus which causes swelling and inflammation of the surrounding area. In case it happens to be an abscess, the physician would drain the pus collection and clean it with antiseptic solutions and prescribe you antibiotics depending on the bacteria involved. Visiting a physician as soon as possible is essential as the bacteria can invade further deep and reach the bone and lead to further complications.
Hope this information was useful.
