I have a spinal disc herniation l4-l5 and a severe left leg pain. I'm trying to avoid surgery, doing exercises, but will it heal on its own? Mri att

Pinched Nerve. It can take up to 6 months to go away on its own. I would suggest seeing a pain/spine specialist to evaluate you further to evaluate what level and what can be done to treat you. There are interventional treatments besides medications and surgeries that might reduce or eliminate the pain altogether.
It depends. If you are not suffering from disabling recurrent low back pain, you may take the conservative nonsurgical approach as you are doing. Most pain from minor herniated disc improves from physical therapy, nsaid, proper sitting posture and avoidance of over straining. Herniated disc may persist.
Wait for 6-8 weeks. If no relief after 8 weeks and herniated disc is also on left side and co-relates well with the symptoms then you should consider surgery. Usually surgery will relieve leg pain but back pain may persist.

Might need surgery. A herniated disc is one of the most common reasons for needing back surgery, especially if it is causing weakness or numbness in the leg. See your doctor and get a consultation with a spine surgeon (usually an orthopedist or neurosurgeon). You don't want nerve problems to become permanent. A microdiskectomy can sometimes be done as day surgery. Hope you feel better. Read more...
Exercise is always . The first line of treatment for any herniation. Surgery is never good as advertised especially in a young person. Most disc herniations improve over time but it can take 1-2 months. I tell my patients to start a gradual walking program. If you can walk 3 miles (about 5 k) you should be ok. Other sue steroids, steroid injections and/or surgery might be needed. Read more...

Would a central disc herniation l4/l5 cause leg pain or just back pain? Please help! Thanks

Often times both. I've answered questions for you on other occasions though I don't recall this category. A disc herniation at L4/L5 could cause both back pain as well as result in radiation of that pain down nerve root distributions which go into the leg.
