Hello. Thanks for asking from HCM.
I can understand your concern. The tightness in calf can not be due to L5-S1 nerve as
nerve damage here will cause soft, flaccid calf. However cord damage at cervical region (C4-C6) can cause tightness in calf.
The pain in right leg and sensory loss in middle toe can be due to both or either.
To differentiate between two conditions, check whether
: you are having tightness in all
limbs, it suggest cervical cord compression
: you are having pain in lower back till foot, it suggest L5-S1 nerve damage
: Involvement of other extremities suggest cervical involvement.
Also if you are doing too much exertion of lower limbs, this pain could be due to exertion. I think you can now reach upto some conclusion.
Meanwhile at home you can follow few tips :
: Take rest
: Take
Diclofenac sodium for pain relief after proper prescription
: You can apply warm compresses over calf to relieve pain and tightness.
: You can stretch your calf.
Thanks. Hope it will you. Take care.
