I been taking clindamycin for two days now i'm starting to get streaks of red itchy lines feeling as if it is a vein?

Show a doctor now: Red streaks could indicate an 'uncontrolled' infection - such as if the clindamycin is not strong enough or the infection is resistant to the drug. Alternatively, if you have itchiness - it could be a drug rash. The best way to decide is to show this to a doc. I would call the prescribing doctor now, and/or send pics to Health Tap so someone can give you an answer now. These things can worsen BTW.
