Welcome to the forum. The nose bleed that you are complaining of can be due to some infection in the nostril or dry sensitive skin that has a tendency to crack and bleed. This often happens in winter or windy season. Avoid going outdoors without proper protection in such seasons. It can also happen if you have been taking medication, "warfarin".
Fluatuation of your blood pressure indicates poor general health. Have a health check done to rule out any diseased condition with which you are not aware of.
Take balanced iron, calcium rich home diet. Dairy products and milk will make up for any calcium deficiency
. To rule out the stiffness
of your body you can get blood tests done to know your RA ( rheumatoid artheritis ) factor and thyroid
levels. Stffness of your body is due to lack of exercises or any type of anxiety

For the leg pain apply anti-inflammatory oitments or spray. Taking NSAIDS for a long period may cause side effects. Take care.
