There isn't sufficient information to reach a specific diagnosis, but there's a possibility it could be due to trauma to the collar bone that may have caused a fracture or cervical spondylitis causing a referred pain. Ideally you should visit an orthopedician so that you can be examined and undergo investigations such as X-Ray, MRI(if indicated),etc to find the underlying cause and have it treated accordingly. You will require a painkiller, an antacid and a topical painkiller. These following steps may help:
- Apply ice over the area initially to reduce an swelling that is present 3-4 times a day
- Apply heat over the area with a hot water bag or a hot towel so that the muscles will be relaxed and then you can apply a topical analgesic over the area and massage it gently
- Do not carry any heavy weights until the pain resolves
If the pain persists or worsens visit the orthopedician at the earliest.
