Yep. Gotta watch out for the meds. Theyll creep up on you.
Yall need to see your pcp. Falling is not normal, yall can really hurt yourself. Please get that checked out.
It is common, especially if you dont have strong core and stabilizing muscles. A physical therapist can help immensely. Not exercising regularly, but in a controlled manner, will make your symptoms get progressively worse. It is imperative that you do what the physical therapist teaches you at minimum 4 days per week the rest of your life if you dont want to become confined to a wheelchair.
Yes, it's common.
Falling! That is not common or normal.
