Hi,
Welcome to the ehealthforum and I am really glad to help you out.
The symptoms are suggestive of musculoskeletal symptoms or pinched nerve rather than carpal tunnel syndrome.
Give rest to your hand and try not to lift any heavy weights with the effected hand. Try an anti-inflammatory medicine like diclofenac to relieve the pain but it should be taken under medical guidance. Heat compresses may also help. If the symptoms persist then please get evaluated from a physician.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
