I haven't found anything to help except pain relievers sometimes they don't even work. My Neurosurgeon told me to lose weight which seems to be every doctor specialist mantra these days & not look for the cause of why we have gained weight. We don't won't it so why would we have it if we could get rid of the excess. I just find its a cop out & no help whatsoever.

I have several of them.3 in my neck,1 down by L5-S1;and L3-L4.
I use ice packs,heat,and alevae/ibuprofen/naproson/any anti inflammatory over the counter.
Physical Therapy,Chiropractor,sometimes you can get steroid injections depending on how long you have been seeing you orthopedics.

I have bulging disc in neck. I put warm compresses on it and Advil. I have had to go to ER on neumerous occasions to get injections in head due to nothing working.

I find that heat helps, so does the TENS machine, gentle floor exercises

Ice, massage, TENS all help me as does gentle stretching . Heat increases my pain. Everyone is different, try a few things and find what works for you.
