Brief Answer: Your treating doctor is right Detailed Answer: Hello, Thanks for choosing health care magic for posting your query. I have gone through your question in detail and I can understand what you are going through. I understand that you are suffering from a trapped nerve. However spasm in the hand muscles cannot occur due to nerve entrapment. Especially if it gets better when you staraighten your hand with the other hand. It seems you are having quite a relief for entrapmet after the steroid injection. Coming to the hand cramps, the common causes are dehydration , hypocalcemia, writers cramp etc. Many times dehydration alone can cause such cramps. You should be properly hydrated and do drink plenty of water. As it is occuring plenty of times then it would be advisable to do a blood calcium levels. Reduced calcium levels can lead to such cramps. The same needs to be added orally. The last common cause if there is no dehydration and calcium levels are fine , is writers cramp. It requires some independent physiotherapy to improve it over a period of time. Hope I am able to answer your concerns. If you have any further query, I would be glad to help you.
