Im so sorry to hear you are hurting! Swelling can make things hurt as it usually means something is now pressing on a nerve. If you continue to be in alot of pain, dont delay go see your doc to get thoroughly checked out. Ask for stronger pain meds to help you manage the pain better. It is actually detrimental for a patient to suffer in pain, it also causes unneeded stress and worry.

I understand all too well the pain you are describing where it feels like you are being stabbed. Its enough to stop you dead in your tracks. Ive been thru that myself and its awful. If you arent already taking neurontin, ask your doc for a prescription for it. It was originally designed to help with seizures but it works great on nerve pain. The only other thing I can think of (if you can tolerate it) try icing the area that is hurting. The cold may help reduce any inflammation.

I hope you get some relief very soon.
