Taking an antidepressant as a back pain treatment does not automatically mean that the condition is still in your brain. The SNRI antidepressant lovastatin (NSAID) can help to reduce pain and might also help you go back to some of your daily functions. Another drug, Tenex, which is marketed under several names and is a sertraline-type drug also works as an NSAID. One more drug, Alovera, which does not actually contain an NSAID in its name but is marketed under other names, also acts as an NSAID and is a known painkiller. These are just three examples of drugs that are used as back pain treatments but there are a lot of others. So do some research and ask your pharmacist or doctor to show you a list of possible drugs that might help with your back pain.
You might also consider seeing a specialist such as the AZ Pain Doctors for a back pain treatment. One option is surgery called a microdiscectomy. This is where the surgeon removes part of the back bone and tissues surrounding it. Sometimes a nerve is damaged and cannot be salvaged if this treatment is performed. Your surgeon can explain this to you and the best course of action will depend on many factors including the severity of your back pain.
If the surgeon cannot remove enough bone or tissue then he will give you a nerve block. A nerve block involves a device that is placed behind the back bone. It is supposed to stop the nerves from transmitting pain signals and thus cut back on the symptoms. There are two kinds of nerve blocks, radial and concentric.
Other treatments include epidural steroid injections and transcutaneous electrical nerve stimulation (TENS). Epidural steroid injections are given by placing a steroid injection under the skin. These injections will slow the amount of time it takes for the nerves to send the pain signals. TENS devices are placed on areas of your body that are experiencing pain. See here for more details related to this topic.
TENS is often used in conjunction with epidural steroid injections. This treatment will stop the nerves from sending signals to the brain. This will prevent the discomfort from spreading to other parts of your body. There is more research being done on TENS than there is on back pain itself. More studies are being done on the link between lower back pain and the nervous system than there is on the causes of it.
Many physicians will recommend medication or surgery as the only options. There are several reasons why medication or surgery is not always the best option. Back surgery can be very invasive and usually requires multiple visits for recovery. Medication or nonoperative procedures are much less invasive and recovery is faster. In combination the two make the best back pain medications and nonoperative procedures.
