welcome to HCM!
I have read your query carefully and from my clinical experince I can say that you should see a neurologist
, get a scan of your spine.
The problems you mentioned and the accident seem to be related.
So, please fix an appointment with the doctor and get your self examined.
#### Avoid any strenuous movement, avoid pulling weight, and bending to much till you seek treatment.
Only after proper tests, one can give appropriate drugs.
Hoep you get well soon
feel free to ask more queries if you have
