High BP post delivery. Bp medication.

Hi, I got high BP post delivery,used BP medication for 6 weeks .After 8 weeks, I was having giddiness and weakness.Consulted gen physician,he checked my BP and asked me to continue BP medication for 2 months.At 10 weeks , I started getting numbness in whole body,was feeling restless , sometimes shortness of breath and extreme  fatigue .Consulted neurologist and had following tests.CBP,urine test,2D echo and brain MRI.All reports were normal .He prescribed few medicines for numbness and pain along with BP medicine. It's now 4 months,BP is normal now .Had review with neurologist and he asked me to continue the medicines for 2 more months. He says my BP is chronic now and have to continue BP lifelong. I never had high BP before delivery, does postpartum high BP will not subside and I have to continue BP medication.
