I have had tingling/numbness in my finger tips since july 13 and I take copaxone (glatiramer). I wanted to know is there a medication to stop numbness?

Need a diagnosis. If the numbness is due to ms, you may be experiencing a relapse, and that could be treated with a steroid or acth. If the numbness is due to a peripheral nerve issue such as carpal tunnel, this could be treated directly. You need to discuss with your doctor and search out the etiology and then address with specific intervention. You see, ms can co-exist with other problems and these need eval.
Numbness. The tingling or numbness if your finger tips may be due to an impingement problem. Consult your doctor for a possible xray of your cervical spine.
