Dehydration at a minimum is suggested by your symptoms. Definitely of concern if condition causing your symptoms was not diagnosed properly. You should consider a visit to a local urgent care at a minimum, if not local emergency room. If being established with a local doc that will be your best starting point.

Agree with Dr. P. Dehydration is a likely culprit. Drink enough water, fruit juice or electrolyte drink so that your urine is mostly colorless. Wish you good health!
