Why are my friend's feet causing trouble?

Your INACTIVITY caused muscle weakness, leading to lower back pain.. The pain could now be radiating down your legs as numbness. The numbness in your legs could be due to nerve damage. You need to consult a DOCTOR who will assess your condition and advise you accordingly....

The bulging discs at L4-L5 and L5-S1 levels might be a reason for the nearby nerves to get compressed which would have caused the pain. Sometimes, resting, physical therapy, and pain medications can help manage the problem. In cases where the pain is severe and other treatments don't work, surgery can be an option. Generally, you should keep your body safe and abide by your doctor's orders to discover the most effective method for treating your back pain.

You might have muscle pain coupled with pressure on the neck and the shoulder region. Muscles are likely to be tensed or strained bringing about such signs. The issue of muscle dropping below your clavicle and squeezing your neck could result from sitting or standing with drooping shoulders. You can ease them by keeping the right body posture always, engaging in mild stretches that won’t hurt much, and using warm towels on those affected spots. 

Did you consult with neurologist or orthopedist? If not then please do that. They can diagnose the underlying cause of the sciatica and provide appropriate treatment. Some self-care measures such as taking over-the-counter pain relievers, gentle stretching, and hot/cold compresses may also help to get rid of the symptoms. However, these measures should only be used under the guidance of a doctor.

When your shoulder tendons have tendinosis it means they're damaged. Doing too much with your arms or just getting older can cause it. The time it takes to get better is different for everybody. As long as you take the medicine and do the physio that should help. Pain can come and go while you're getting better, so don't worry if it starts hurting again. Feel better!
