I hit my shin on some rocks down by a stream about 3 months ago.It was open and a scab formed over it. It closed but I noticed that It fills with a clear fluid and is still very much black at the point of impact. However no pain or blood, just a thin layer of skin that fills with the clear fluid.
Hello, thank you for your contact to Chat Doctor. If I am your doctor I suggesting you there is two possibility of such a fluid first is hematoma which is black, it has blocked the passage to fluid go away, which is shown as fluid filled area. Second possibility is infection. You can start with antibiotic like definite, analgesic like diclofenac and partaking tablet. Locally you can use juridic acid ointment. This remedy is helpful to you in both cases. If you have to ask me anything you can contact me. Chat Doctor. Infectious disease specialist. Thank you.
