[|AI|]  Hello, Your symptoms seem to be related to bursitis. Bursitis is inflammation of the bursa. A bursa is a small sac of fluid that cushions a joint and helps it move easily. Bursitis usually gets better if you avoid the activity that caused it. Meanwhile, I suggest using anti-inflammatory medications such as Ibuprofen to relieve the pain.  I also suggest using cold compresses for local applications. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
