“How long will sciatica take to heal?”

Not heal but correct

I specialize in treating these types of cases, often using a technology called "Non-Surgical Spinal Decompression Therapy". In our clinic, we most often combine chiropractic, massage, and other therapies/exercises, as appropriate, to ensure the best possible outcome. Unfortunately, there is no one-size-fits-all answer. Each patient must be carefully checked to determine the specific cause(s) of their problem, and each component is addressed with specific intervention(s). Additionally, there are often numerous contributing/complicating factors, such as underlying health conditions that could impede healing, body weight, postural "defects", work and exercise habits, and, of course, the severity of the patient's condition. (How bad is the disc? Is there any degeneration/arthritis... and how bad? Is the patient on any medications? etc.) After a thorough evaluation, and sometimes a trial of treatment to monitor response to treatment, the astute doctor will be able to give a more specific time frame for healing. To get a specific answer to your question, get a detailed examination by a qualified doctor, and one who specializes and has a proven track record of success.

It depends on the cause, and your treatment. Usually about 4-6 weeks.

With the proper care, i.e., spinal correction adjustment along with physio-therapy, with micro-current, 2-3 weeks.

First, is it due to a disc problem or a piriformis syndrome? This can determine the overall healing time. Under Chiropractic care, most patients receiving treatment 2-3 times a week usually will see some relief fairly quickly. if it is due a disc problem, that can very depending on the severity of the disc damage.

8 to 12 weeks or more

That really depends on you. If you have sciatica, you should get professional help from a chiropractor or other provider that specializes in this. They should do a thorough exam after taking a detailed history, make a proper diagnosis, and make appropriate recommendations that may include exercise, manual therapy, perhaps dietary or lifestyle changes. The sooner you get help, the easier it will be to treat.

If you’re in severe pain, I usually recommend treatments daily until the pain becomes bearable. Usually in 5-7 treatments the pain comes down significantly.

Sciatica is a symptom, not a diagnosis. Sciatica will not heal until the issues causing it are addressed. I recommend consulting a Chiropractor to find and treat the cause of your pain.

To answer that accurately, I need more info/data. Such as, how long have you had it? What caused it? Was it a trauma injury, fall or came on gradually or sudden. That is probably the most common condition I see as a chiropractor over 40 years. Chiropractors get good results if the sciatica is from a structural cause in the spine. Start with a consult/exam, weight-bearing (standing up) c-rays May be needed. In complicated cases, even a lumbar MRI may be used to confirm disc involvement or not.
