Your symptoms may be suggestive of chronic ill health in the form of chronic fatigue syndrome, anaemia, deficiency of vitamins etc. Also for the pain in abdomen and frequent urination you should check out with a gynaecologist for an examination. If necessary and ultrasound scan may be done. Discuss with your Doctor.
Hope this helps.
You should get these tests to rule stuff out - blood test - for thyroid, diabetes, CBC and vitamins too. You could be tired for thyroid or diabetes or vitamin deficiency. STart taking vitamins. Get a cat scan or ultrasound. You could have back pain from kidney/gall stones too. It could be an easy thing so dont pain. Cancer for ovarian is CA125 blood test - ask if they will do that too. Always get copies of your reports and tests and ask them to be explained to you. Keep looking for a reason. Maybe you have allergies and if so go to a dermatologist or allergist to find out. GOod luck.
Also the frequent urination could be a urinary track infection - it happens, and it could be very painful on the kidney on the left side which is where it may be.
