Thank you for posting your query.
The symptoms are suggestive of minor involvement of the left ulnar nerve, and resulting weakness of muscles supplied by this nerve.
In most cases, the condition is self-limiting, and spontaneous improvement occurs.
As of now, nerve vitamins such as B12, folate, alpha lipoic acid may be taken.
Physiotherapy with exercises is also helpful.
If any pain or tingling occurs, then, pregabalin would be useful.
Please get back if you have any more queries.

I recommend an ER visit. An Xray for the arm might be needed. As Dr.Sudhir suggested there appears to be an ulnar nerve compression which can spontaneously recover. However any fracture or external compression needs to be ruled out.

Additional info: I fell on my elbow about an hour before the second fall. It's sore and tender to the touch, but not especially painful.
You can take pain medication like Ibuprofen (400mg two to three times daily) for pain relief. This will help in reducing the swelling and inflammation too. But you do need to get it checked for fracture or serious nerve injury.
If the hand symptoms are persisting it need some evaluation as I have mentioned earlier.
