Hi, I feel really sorry for you. May God help you find the correct diagnosis & treatment. Although all this do not seem to be related to your miscarriage
but to be on the safe side I suggest you check your blood BhCG levels. If that comes out to be normal we cannot relate your symptoms to your miscarriage. If God forbid results are positive you need treatment by a specialist gynecologist. In addition you MUST consult a neurologist
& request a CT or MRI
scan of your brain to rule out any lesion there. I hope all this help you find out the cause & proper treatment. Good luck.
