I suffer with sciatica pain and severe pain in my groin .... what can i take to relieve some of this pain ?

Several options: Note you are trying otc preps, which may help, but your nerve pain could benefit from Lyrica (pregabalin) or neuron tin. A Butrans patch is a narcotic used once weekly with minimal risk factors, and long-term analgesia.

May try predinosone: Warm compresses, massage, back strenghtening, excercise, nsaids muscle relaxants and predinosne. May use narcotics but be careful with developing dependence.

Spine Pain Options: This chronic pain in the distribution as you suggested is the result of an irritated nerve or facet joints or other injury typically in the lumbar spine (low back) which are caused by herniated disks, spinal stenosis or degenerative disc disease, etc requiring further evaluation by a spine specialist and may be candidate for facet injections/radiofrequency ablation and epidural steroid injection.
