hi,
thanks for providing the brief history of you.
kindly first focus on getting the knee fixed. for which you may have to take an
MRI scan to find the extent of
injury. once assessed you can contact a physical therapist for the same. he will help you with multiple exercises which will make your knee stronger again. Post that a regular exercises along with the guided physical therapist will even help you get back to shape. along with this whole process your
metabolism will improve as well. The physcial therapsit may use
TENS therapy over the neck region and your
migraine pain may come down. I have personally made a try on it and it has helped alot. Next is to strengthen the muscles of the neck which can hold the head without any lag.
now coming down to migraine. Certain times improving the metabolism of the body can help reduce the symptoms of migraine as I have tried on my many patients. A combination of
meditation, breathing exercises, strength conditioning the most part of your problem should get solved.
taking a lot of medication may not turn out good over a long periods. weight is not a problem, but the problem is how the metabolism works.
with the grace of God I wish you a speedy recovery.
