The spine surgery (L3, L4 fusion) and fracture­d tailbone might be causing your persiste­nt discomfort. Let's look closely at your MRI scans to figure out what's going on. I sugge­st consulting an expert spine doctor for a thorough che­ck-up and tailored treatment plan.

Back and neck pain can have various causes, including poor posture, muscle strain, injuries, degenerative conditions, and stress. Consult with a specialist for personalized recommendations for treating your pain. In the meantime trypracticing good posture, gentle stretching exercises, applying heat or cold packs, and stress management techniques may offer some relief.

Joint pain, swelling, and stiffness are some of the symptoms of rheumatoid arthritis. Steroids can be used to reduce inflammation in the affected areas. In the case of a healthy diet, one should eat more fruits and vegetables which contain vitamins that help fight diseases. Additionally, an individual can consume whole grains such as brown rice or oatmeal since they have fiber for easy digestion. Foods with high protein content like fish or beans should also not be left out. To promote general body wellness, patients should avoid taking processed sugars and other similar products. By so doing they will be able to manage most signs related to this condition.

When you have an ACL tear, it is because the ligament in your knee is overextended. In addition to resting and doing some light exercises, you should ice your knee. Although PRP or stem cell therapy could be useful for a speedy recovery, consulting with your healthcare provider on these treatments is the best way to determine the optimal care for your case. 

An ESR test me­asures inflammation levels in your body. A lowe­r ESR reading, like 26, indicates le­ss inflammation compared to a higher value like­ 70. This suggests the inflammatory condition is relative­ly better controlled. Ankylosing spondylitis cause­s back pain and stiffness due to inflammation in the spine­. Effective manageme­nt involves staying physically active through exe­rcise routines, adhering to pre­scribed medications, maintaining a balanced die­t, and avoiding tobacco use. 

You may be suffering from a blood clot in your leg as a result of the accident. Injury to the leg causes blood to pool and form a clot causing swelling, redness, and pain. This is serious because the clot may break free and travel to other parts of your body. Elevate your leg above your heart, apply ice, and take a break. When the pain persists or becomes severe, go to the nearest hospital immediately.

Regarding what to expect 5 months after knee replacement - If there are no complications then you can work freely as per your wish.

But after knee replacement, some patients do not recover as quickly as others. Consider the following:

• Patients who conducted knee-strengthening activities before surgery have a better chance of recovering faster.
• It may take longer recovery time for those patients who are older, smoke, or have other medical concerns.

Note: Although deviations from the "normal" recovery timeframe is not always expected, but such fluctuations are usually acceptable as long as the patient, doctor, and physical therapist continue to collaborate in the pursuit of a complete recovery.
