[|Human|] Hi,I went to the dentist to have a tooth removed.After the surgery, the dentist gave me an injection in my right arm, probably for the pain.It made the injection site swell and become hard.Its been 2 weeks now and the site is still swollen and hard.Whats the cause of this and what can I do
[|AI|]  Hi. Thanks for the query. As per your complaint swelling around the injection site that has become hard can be most probably due to accumulation of blood under the skin due to broken blood vessel. At times there is Hematoma formation that can take even months to resolve. Hematoma is a harmless tumor like mass formed due to spillage of blood from ruptured blood vessels leading to accumulation of blood into the soft tissues forming a lump. I would suggest you to do alternate warm and cool compresses over the swelling. Take pain relievers like Ibuprofen as they also have anti-inflammatory action. Keep moving the arm to avoid stiffness. In case if there is no improvement in another 115 says or if the symptoms worsen consult a Local Physician and get evaluated. Hope this information helps. Regards.
