hi,
thank you for providing brief history of you.
Looks like you have too much pain which is not allowing you to move around. Why don't you just see a doctor once who can help you by some medicine for symptomatic relief. Its never bad to take an experts advice.
Also, in the mean time you can start some exercises which will help you to a certain level of your pain.
Start with simple breathing exercises and steam inhalation. Why i am mentioning this is because when the body is weak it needs more energy and the biggest source of energy for a cellular mechanism is the
oxygen. The more the oxygen the more the cellular mechanism to its best.
Also, when you do breathing exercises, it will help nourish the cellular levels of muscle tissue which will make you feel better.
Slowly try performing simple hand and leg exercises while sitting and lying down on the bed. It will make the muscle mechanism of contraction to function by which the muscular tissue physiology will be activated and the oxygen will help the tissue nourish.
Later on you can go for short walks and try doing simple jogs at a constant place.
If the bruises are not coming down you need to check with the
dermatologist as the skin has to be examined for any particular infection.
If you have more questions you can ask me directly anytime
