What Causes Tingling Sensation In Left Arm And Leg While On Methylphenidate?

I m 20 years old (male) and was recently prescribed methylphenidate for ADD. However, I ve been taking the maximum daily amount since I ve been prescribed (60 mg per day). However, I spread this out over the course of 16 hours usually. Today, I ve been experiencing tingling in my left arm and left leg with slight numbness and muscle weakness/shakiness in left leg. My chest was a little tight earlier but seems to be fine now. Is this something to be overly concerned about?

General & Family Physician,  's  Response
welcome to hcm,
I really appreciate your concern,
No methylphenidate cant cause tingling and numbness though it can cause mild tics,
The pinprick/tingling sensations in your limbs are indicative for compression of nerves root coming out from the vertebral spine.

Neurological examination and MRI of spinal cord will help determine current changes and at what extent the nerves root are affected.

2. I need to know if diabetes is ruled out?

3. Next, I want to know if your doctor asked to run arthritis testing to rule it out?

4. are vein problems are ruled out? Have you had any Doppler ultrasound so far? Can you please provide the report?
5. also do vit b12 testing which defeciency can cause tingling as a peripheral neuropathy.
As you may see, if I was your caring doctor would rule out :
- the metabolic diseases first including: diabetes, thyroid, arthritis,etc.
- then, discuss with neurologist to rule out neurological issues
Please let me know if you have any questions,
thanks.regards.
