Re: L5-s1 microdiscectomy
Unfortunately this type of nerve pain can last a long time, particularly if the nerve had to be manipulated during surgery. Nerves are very sensitive and do not like to be handled. Due to your calcification, it sounds like the doctor had to do some tugging to free the nerve.
The dural tear would cause a headache but shouldn't affect the amount of nerve pain you have.
It is fairly common to have some swelling of the foot or ankle post surgery. There is always a small chance it could be caused by a blot clot, but usually it is just a side effect of the hospitalization, etc. that will go away with time.
Did the surgeon prescribe a drug for nerve pain like neurontin or lyrica?
