Brief Answer:
There might be indirect relation- advises given for both

Detailed Answer:
Hello,
Thank you for asking at healthcaremagic.

I carefully read your question and understand your concern.

Plantar fasciitis might become sometimes challenging and needs regular visits and different treatments to have some effect.
Pills and injections might help release the pain and are tried often. Sometimes physiotherapy added to those treatements is needed for better benefit.
You need to make sure you have good supportive shoes, maintain healthy diet, stretching of the sole and calf and applying ice might help also.
I don't think there is a direct connection of plantar fasciitis with the leg pain but when we have pain somewhere, trying to protect that area, we might be overstressing other areas and cause pain away from the first painful area. So the pain you have in the leg might not be directly caused by plantar fasciitis but it might be indirectly related due to compensating adjustments for the painful walk with fasciitis.
If you don't have numbness or weakness of areas of leg or foot than it is less likely it is a nerve being pinched and simple muscular pain is possibly the cause of the leg pain also.
Both fasciitis and the leg pain might benefit from physiotherapy so i would recommend you to see a physiotherapist that will give you the proper exercises to relax the over-stressed muscles and tendons and help with the pain.
Continue with the oral pills to reduce inflammation while you have the physiotherapy, this will help you improve quicker.
Sometimes adjusting the shoes might be a help also, adjusting the arch of the foot- the physiotherapist will tell you if you need this.
Night splints might be tried if these do not help enough, so to keep the foot stretched. Your doctor might prescribe those.

Avoid sports like running or jogging but cycling and swimming are easier on the foot and do not irritate as much the plantar fasciitis.

I hope this is helpful and answers to your question but please feel free to reply in case anymore clarification is needed on this.

Kind regards,
